  1. I ordered different times tyres at Renn Reifen including the DUNLOP DZ03G when they used to be available in 285 They are not really fast to reply emails etc and when I wanted to order some Hankook they then wrote that they were out of stock and I asked about Federal ant they were again out of stock and ordered the Trofeo R but after that they did not update their website so either some of the tyres are available or they just do not update the website I think that the dunlop is not available anymore in 285 The Michelin pilot sport cup 2 is an excellent all around tyre with a lot of grip for the road good on track and without many dowsides of the usual semi slicks But if you want to be really fast and agressive on track there are many faster and better tyres that will feel more made for the track The michelin is good but not as fast as others (Trofeo R for example) if you continue pushing it can become a bit greasy and squeaky and also (by doing a few powerslides at the end of a session) It can delaminate But still it s a very good tyre depending on the driver use and conditions.... It s cheaper than some others good on street not noisy not that bad on wet for a semi slick and will last long if not pushed to the limit on track The dunlop DZ02G and the trofeo R (each on a different way) made the car feel a little more as a racing car
  2. I used the MPSC2 the DUNLOP DZ03G and the TROFEO R on the 380 cup I really liked the Dunlop DZ03G they are really good and even if they feel different I think almost as good as the trofeo r (maybe less good on wet) The problem is that they are not available anymore in 285 and I can only find them in 295 and as they are quiet a wide tyre I think they might be a little too wide Does someone know where to find them in 285? I saw a 380 cup fitted with A052 in 215 and 295 and the rear tyre look just a little too wide but I would think really acceptable and they should be good on track
  3. Ok but let s say you get somehow access to position C Where would you fit the rubber pucks for the front in position B ? In that case the problem is that for the common size scissor lift the B raising points are too inwards and not reachable.... or you would have to make some custom center bar Or would you suggest to use C and A even if they are close? Is it possible to use those alloy cylinder pucks sold in usa to fit them on the car to extend the C raising points? I know they are made for the exige s2 and don t know if they would work on the s3 Thanks
  4. I fitted on my 380 cup some trofeo R in 225 front and 265 rear The 225 front is fine even during track use but is a bit taller and will slightly rub at low speed if you are at full lock BTW I have -2.2 front camber The trofeo R at rear in 265 is wider than others 265 so it s ok and I think the trofeo R in 295 would be a little too wide on standard rims and it s better to have a look at the specific tyre spec I saw another 380 cup fitted with the yokohama a052 at the rear in 295 and they are just a little wide on the rim but I think acceptable 215 front and 285 rear is still I think the best sizing but not many tyres available If you dont want to use 265 rear tyres or tyres available in standard size than I would go for a052 in 215 and 295
  5. Something really useful would be if someone who fitted a KT 460 kit and had the dyno made at their shop would then make a comparaison run on another dyno... They seem to all have near 460 at their shop dyno... I m not saying that the KT power kits do not make the expected difference... when fitting the 430 kit my car was running fast and it made 40 bhp more on the dyno... But I m really questioning Lotus oem power output especially on the 380 versions... My 380 cup was around 345 bhp on the dyno and 385 bhp with the KT 430 kit on the same dyno... After that I fitted the KT 460 kit but did not had it on an independent dyno but for sure it was not feeling 75 bhp more... I would expect at best another 30 bhp

  7. If you talk about a scissor lift with full length arms where the car wheels are on lift or one with extendable arms or by somehow removing the rear panel and reaching the rear lifting points maybe... But with a normal scissor lift with ramps between the wheels as in the link and as described yoy can t just park the car use 4 pucks and lift it as you would do with another car... You can do that I think with a 4 cylinders but not a V6 But to understand what you mean post a picture of a V6 on a lift
  8. The exige V6 can NOT be lifted with those scissor lifts in a normal and approved way.... Be careful as if you lift an exige v6 the rear end weight distribution would make it fall from the lift also have a look at the lotus documented lifting points and how they work as you should not just use the 4 center points indicated by stickers on any type of lift
  9. Just a few things to keep in mind in no particular order I own a cup 380 and I fitted a Komotec 430 kit then upgraded to the 460 kit... Dont want to repeat it but as already wrote I broke the engine two times once when completely standard (on track at 2400km) and the second engine (new from Lotus) after fitting the Komotec 460 kit (on track at 4500 km) The second engine broke a piston on track but started to smoke slightly black on acceleration before but the good think is that nothing else broke and I could just rebuild it with forged parts. Not to argue if caused by my use or not but the standard internals and especially pistons are not really strong so I would at minimum say that if they can be used until 500 bhp really depends on the use of the car... (I think nothings wrong at all with komotec kit and probably did not cause the problem the standard pistons are weak even with oem power) For some unknow reason (electronics mapping temperature other) it seems that there aren t a lot of failures of the oem pistons on the charge cooled later versions as the 430 cup even if the oem pistons are the same pistons... I would say that the 430 Komotec kit is really a good bang for buck The tvs 1900 even not chargecooled can give easely 430 bhp with an exhaust airbox and custom tune... and you really feel that it has more low torque compared to the 1320 Don t know how much you loose on track when weather is warm but still better than the smaller supercharger Even if I m not so sure about the numbers of Komotec at their local dyno (did anyone had a dyno at komotec and later on another dyno?) as the standard Lotus 380 are usually not making all the power they should I have to say that the power difference was there (40 bhp more form standard to komotec 430 kit) on another dyno Not that easy to get power with just a pulley and a tune on many models... You should consider that the oem catalyzers are not really ideal they keep a lot of heat and if they brake they can damage the engine (as you can read on 2bular website) On the 380 the standard rev limiter was lowered to only 6800 rpm and many tuners do not offer a map that will bring it back to 7000 or 7200 rpm (at the moment only Komotec ) If you make the supercharger spin faster (and lotus already did that on the 380) you will heat the air so especially on track it will be worst after a few laps The recommended fuel for a standard car and even more far a tuned car is 98 and I think that those cars really have to get good quality fuel also because Lotus did not change anything from the oem normally aspirated camry v6 engine (compression ratio sensors etc) but they added a supercharger and a lot of power so that made it weaker if used with less good fuel... Each tuner as komotec SSC and others have a different approach and they offer in fact good products but they also have to deal with a very special market and deal with the oem weak points of the lotus cars... What can they do if the oem 380 is in fact not 380 bhp on a dyno and the pistons of toyota aren t really strong? If they would say that every car should be fitted with forged internals and then a whole lot of expensive parts to technically work properly many would just go somewhere else or keep it standard
  10. Hi On the exige 430 cup the electronic throttle body should be bigger than on the older models as the 380. I was wondering if the intake parts are still the same on the 430 cup with just some kind of adapter or if even the standard intake piping is bigger or different and what about the afm? Does anyone know if the bigger throttle body is plugged on a 380 it will be recognized and working (of course with a custom remap) or did they change some of the harness?
  11. Hi Jack Thanks for the info I read some of that about the Honda guys mixing synchromesh etc... But was thinking that the Redline was already using similar friction modifiers making the synchromesh mix not necessary. With those manual gearboxes prone to crunching is not easy to find the best possible compromise if using them hard on track... As of course you want the synchros to be not slippery but is MT 90 good enough for higher temperatures on track? When I start to feel the gearbox less good on track I always wonder if it s because the synchros or if because too high temperatures for the oil that I use or both. Will see If mixing synchromesh will make it better... If you have other tips let me know... Other than that stiffer engine and/or transmission mounts like innovative mounts improved the shifting too (especially on the old exige s2) Don t know about SSC cables compared to the latest oem cables that look to be quite good
  12. I am also using redline MT 90 and had some crunching of the 4th gear on track but just one or two times Is syncromesh really different than the addittives that are already in the MT90? Would it not be the same then to switch to redline MTL? BTW I Improved things by bleeding the clutch fluid (and brke fluid) to castrol srf
  13. My Exige cup 380 had a complete engine failure at the track after a correct 1500km engine run in and oil change ant the car was all standard except the auto blip module and a k&n panel filter. It was changed at only 2400 km not under warranty as there was an old record of a mishift to higher rpm peak at 7800 rpm (weeks before the failure) A complete new oem engine was ordered from Lotus and again correct run in of the engine and oil change. Some Lotus tuner told me that if used on track the pistons would probably brake... I then fitted the Komotec 430 kit and the car was working really well and I did a trackday without problems... some weeks later I went to Komotec and they upgraded it to the 460 kit and even if it was working well it was not really feeling better than before and even a little weaker in the midrange. They had to replace a faulty oem o2 sensor while there... I asked about oem pistons to a komotec mechanic and he took a broken oem piston to let me see where they brake and he tought that only a few cars would brake but not depending if oem or with power kit... After only two trackdays (the car started to slightly smoke black from exhaust just before) one oem piston broke... I don t tink it s because of the Komotec kit just that the oem pistons on the newer models are bad quality Now I just had the engine rebuilt with fordged conrods and pistons but the tuner that did the work noticed that both pre cat lambda o2 sensors make an error and should be changed I did not ask him to look if they were plugged right but as Komotec installed them I would think that they are not switched
  14. If you look on the center grille on the front with the komotec 430 kit there should be the chargecooler radiator in front of the normal radiator air flow. As noted by a good lotus tuner in Italy that is not the best placement for the chargecooler radiator as it will take away some air flow to the main radiator and slightly heat the air that go to it. I think those few degrees should not be a problem but it should explain why the engine temperature is a little different. You could if you want change that komotec chargecooler radiator for the oem lotus parts of the exige 410 and 430
  15. The owner of that 380 cup told me that it was just a custom made part on his request nothing that should be on the market
