  1. Hi again, I don't have the paper with me now, but if my memory is not wrong I have now front -2.4 camber 0 toe, rear -2.1 camber 2 toe in. For getting -2.4 at the front I had to mill the arms, plus I milled the fiberglass whel archs to not touch with 225 Trofeo. At the rear -2.1 is the max I can get. I know others can get more than that but not on my car u fortunately. Anyway I think current camber, toe, height of car is OK. Regarding tyres I have now 225/265 Trofeo R, however they FINALLY made 215/285 size for Trofeo and I am really curious to try that because that is the original size of tyres on my car. The width of Trofeo R tyres is generally bigger than the measure i dicated, so the 215 will be probably a 220 and the 285 a 290 or so. Anyway, I think that we can discuss about these things for days and not get to convergence. If we really would like to get best setting out of this car we would need to rent a professional driver and mechanic on track and let they play with setting (and tyre size). Of course this would be economically inefficient plus perhaps what fits that pro driver would not fit us.. I can tell you that both the last two coaches that tried my car on the Nordschleife immediately recognized the problem with trail braking. One of them also said that perhaps it is just the controls that are too aggressive and if I would turn them fully off perhaps the problem would disappear.. but on the nordschleife I don't feel comfortable doing that. I drive in Race mode.
  2. It improved a bit but not a drammatic change. I would say that soft pressure trail braking now works (to some extend) while medium trail braking still does not work (car does not turn). I think perhaps it is just not possible to make this car good on trail braking, due to the weight distribution and tyre size ratio. However I also think this car does not need trail braking that much. The lightness allows for very late and short braking, and that gives always enough room to brake on straight line and then go fast on gas early in the turn.
  3. Hello, I finally decided to remove airbags and 3-points seatbelts from my Exige 380 Cup. Together with this mod I am adding the AIM2 dash as well as custom steering wheel. The only part that I am not happy (yet) is the passenger airbag cover. Not having anymore the airbag I would like to replace it, for example with a version in alcantara, but my dealer told me it is difficult to find same alcantara to cover it. Do you have any advise? Many thanks for any input!
  4. Very sad to hear that.. it actually should be very simple to offer a setting that scale it between 7000 - 9000. Not sure after such a big investment why they do not decide to make a quick simple software update...
  5. Hello Everyone, I quickly went through all this discussion but I am a little bit confused. A couple of question: 1) is the 9000 rpm issue solved? I saw this photo on Komotech Instagram where the display shows 8000 at max (look at 2nd photo, the first one is engine). https://www.instagram.com/p/CVm2YXqInoE/?utm_medium=copy_link 2) is there a difference ordering the AIM from a Lotus dealer, from Komotec or from SeriouslyLotus? In terms of functionalities, and binnacle in particular. My Swiss Lotus dealer told me that Lotus is not shipping those anymore for this year because of the supply chain issue, so there are massive delays with parts. Many thanks!
  6. Thanks @Forthedrive! I am very interested to hear your feedback from Doningtoon. For dry track days I am now running Trofeo R and Yokohama A052. Of course I do not expect the Bridgestone to be close to those on the dry, just good enough to have some serious (and safe) fun in mixed or wet conditions. Also I am not concerned about consumption: at 500 Euro x set, it is OK to replace then after 2/3 track days if necessary.
  7. Thanks for the suggestions! I also saw a video from tyre reviews where it seems Bridgestone Potenza Sport ia also a good option. It is a new tyre so perhaps none has really tried it yet...
  8. One update on this: Michelin PS4S does not exist for 17 inch so it is out of the game.
  9. Hello, I am looking for a "backup" tyre for wet track days. I have excluded "rain" tires because those would force me to take them off if it dries or gets partially dry for 1h or so. The idea is thus to fit them and forget on days were rain is expected for more than half of the time. I have read good reviews of Michelin PS4S but I could not find them available now (perhaps is a size problem?). Do you recommend others? Also, about size would you go smaller (e.g., 205 and 265) or stick to the original size (215 285)? Thanks!
  10. I tried a GT4 at Spa, from RSR. Tyre were done, and in 14 laps certainly I could not learn the car as it deserves, however one point was very clear: compared to the Exige, the Porsche lack tons on the emotions side. Really, the pleasure of driving the Exige was so far ahead of that Porsche that I have no regret and I would not swap them even a posteriori or used vs new. Of course you can more easily drive fast and reach the limit on that car - it gives a lot of confidence. But for track days and having fun I think I made the right choice with the Exige!
  11. Yes, I did that on my old Movit installed on my Audi, but it is a very tedious and dirty work. Plus, if you do a track day you can't do until brakes are hot, and it is very impractical to do during the track day.
  12. Sorry if I post in the wrong place, but I could not find any discussion about the KT-490? Is there a thread? Did anyone in the forum tried it?
  13. Regarding toe, I have now 2.0 mm out (total) on the front, and 4.0 mm in (total) on the rear. This is similar to what Komotec also reccomend, as far as I know.
  14. Shims were all out, camber was maxed both on the front and the rear. I think it was -1.6 degree front, -2.1 degrees rear. Now my garage have milled the front and I have -2.4 there, but I have not tested the car since the modification. Regarding sway bars, I have it on soft at the front and on medium at the rear. What do you use?
  15. Indeed, this has been confirmed by Daniel Schwerfeld, who is a great coach and amazing driver (really!!!). I am not 100% sure, but in my opinion it is about the lightness of the car (particularly on the front) combined with the too small tires at the front (standard 215, now I have 225). In practice, the width of the tire is appropriate for the weight distribution, however when you brake hard you have too much pressure on them and they can't turn anymore. You can see this very well in the Nordschleife video when Daniel brake hard and turn at Hocheichen - the car understeer like crazy and he has to open and release the brake to turn. At Imola this issue was very evident, in practice you need to brake a bit earlier, enter in the turn with small/none brake, or in some cases even with already some gas. It takes some time to get used to it.
  16. Wow - this topic is still alive. I posted that message in January 2018.. more than two years later I have tried the car in race mode (actually I use mostly this mode now) and even without ESP (just once!). I can confirm that the car is very stable in RACE mode, and (in my opinion) the mechanical LSD is really not needed. I know that people who added LSD say it improves the drives, but (again in my opinion) this is very questionable, particularly if your engine is stock. Lotus has done a very good job on my CUP 380 and I do not feel the need of that. Clearly, if you start to add engine tuning (more power/more torque), different tyre size, etc... then the factory ESP might not work well anymore and then an LSD might help. So I would consider that only for that case. The only actual issue I have with my CUP 380 is trail braking. The car does not like brake hard and turning at the same time....
  17. Just fitted 225/45R17 & 295/30R18 TrofeoR on my Exige. Both fits!!! The front touches only when the steering wheel is turned fully to the left (really fully). But that was happening also with the Yokohama 215. Also, when fully turned, between the top of the wheel and the arch there is almost a finger - it seems not so different than the 215 to be honest. I will post some photos later.. so far happy! Just comparing the 295 Yokohama with the 295 TrofeoR I can tell you that the TrofeoR is 5-6 mm wider.
  18. Just fine. No spacer needed - consider that I have the 380 CUP model, so my rear wheels include a spacer by factory.
  19. I guess that 380 cup was mine.. at Tazio Nuvolari I saw another Exige (a 350, yellow) at Hockenheim with 225 & 295 Trofeo R mounted. It was using standard rims, so that size would fit.
  20. Thanks for the quick reply. Can perhaps anybody else confirm that those 4 sensors would work? Otherwise I am also considering to not fit them but in such case I would prefer to disable the light on the dashboard. Can this be done with OBD2, do you know the procedure? Thank you and Merry Christmas! PS: I also found these one that looks similar and in the note it says Lotus Exige https://www.amazon.it/dp/B07GJLK6V6/ref=cm_sw_r_cp_apa_i_dP5aEbJY0EFPM
  21. Hi all, I am ordering a spare set of wheels from Seriously Lotus. On those I would like to fit the same TPMS sensors that I have on the stock one (I have a 380 Cup), but Dave told me he does not have them. Where can I order them on ebay/amazon/others? Is there any specific type of TPMS sensor compatible with Lotus dashboard - or are all the same? Or do you have any different suggestion? About wheel bolts: of course I can reuse the same I have already - however since I use the car only for Track day, do you think it make sense to replace bolts regularly? Many thanks for any help!
  22. This helps a lot: thank you! I am quite oriented on the Komo-tec one at the moment, since I saw so many lotus with it. I will ask a few more information before getting it. Point 3) is actually fundamental! Another advantage of the KT kit would be that front and rear disks and pads will be fully identical, and it will be easier to manage replacements later. I measured: the front is 30 mm (so lost 2mm and should be replaced also because of that). The rear is at 25 mm (lost 1 mm, however probably will replace also it).
  23. I just bought a trailer to tow my Cup 380 to the race track instead of driving it. I was surprised that although I locked the car with the remote key, the car didn't made any noise / alarm while towed... no anti lifting alarm??
  24. On my Cup 380 I recently fitted 295/30R18 Yokohama on the rear withoit modifications/issues. Now the question is: would 225/45R17 fit on the front? Any experience? I have standard forged rims.
  25. Thanks to all for the suggestion. Next question is: do you recommend to replace them with a set of original disks from AP Racing or perhaps switch to Komo-tec kit? From what I see on Komotec website, a complete set would cost around 3700 Euro (including pads). Given that the pads are around 500-600 Euro, the 4 disks are at 3100 Euro. Do you know how much the original disks cost for comparison? And foremost, which one is better/last longer? I am happy with the original AP Racing disks, they lasted long and always delivered good braking, but I don't mind to switch to Komo-tec if they guarantee longer duration and same or better performance. As a note: I already use the PF08 pads on these disks - which is the same Komo-tec uses.
