  1. I always carry a spare set of forged wheels with me to track days since a blown rear tire ruined a trackday in Zandvoort last year. Brakes and Öhlins are given above - but I did not apply any changes to the exterioer bodywork.
  2. a few weeks ago I gave a summary of my deliberations about wether to buy a new Exige Sport 410 or keep upgrading my 2017 Sport 350. As posted before eventually I decided to do the ladder, last week i picked up my Lotus at KomoTec in Mendig and two days later the wether conditions allowed for a first test drive, which was great! I abided by my decision for the KomoTec EX 460 Package (Chargecooler, Manifolds, HJS Kat) without the pulley of the supercharger and without increased boost pressure - basically the EX 390 Kit with chargecooler. The power output is 403 PS and 438 NM - I'am very pleased with that result, because what I intended was my Lotus Exige Sport 350 with the power output of the Sport 410 along with dependable thermic stability. The expense is almost the same as if I had opted for the unmodified EX 460 Kit which makes sense because the amount of work is the same no matter the power output. The car feels much more powerful and handles great - at the end of march I'll be back to Italy (Imola and Mugello with the Pistenclub), I look forward the performance on track and I'am curious about the lap times I can achieve then... Subsequent I post my thoughts from November last year over again just to keep my decision process transparent - maybe it helps evrybody in a comparable consideration process I repeatedly decided to upgrade my Sport 350 which I bought two years ago new from KomoTec in Mendig and I recommend that step by step approach because that way your driving skills can keep pace with the Lotus... Initially I assembled to the brand-new car Öhlins Suspension Kit Track Harness bar and 4 point harness Transmission Oilcooler Motorsport towing eye Forged Wheels After the first year and an few trackdays I added close ratio final drive (highly recommended) Drexler LSD uprated clutch KoBra Brakes fuel cell 60 ltr At the end of this years tarckday season I pondered if I should continue to upgrade my Sport 350 or trade my Sport 350 in for a new Sport 410 and start to upgrade the 410 from the start as well (LSD, close ratio final drive, towing eye, harness bar, fuel cell). Again I decided to upgrade my Sport 350 because (beside the tempting chargecooled Sport 410 engine...) there's to many things about the 410 I don't like (besides the margin betwenn the 410 price tag and the Sport 350 depreciation...), in detail the exhaust noise (to noisy for trackdays) carbon tailgate (ugly to my eyes....) tail lights (ugly....) manifolds (kats) are the same as with the Sport 350 final drive no LSD Michelin Cup2 tires So I recently carried my Exige Sport 350 to Komotec in Mendig, Germany to get the following modifications assembled for the 2019 trackday season manifolds and HJS Kat watercooled intercooler alloy water radiator (not available for my car) That's basically the KomoTec Phase EX390 Upgrade with watercooled intercooler because the charge pressure and the pulley will stay unmodified (approximately 410 watercooled HP expected....) Next year perhaps I will upgrade that setup to the KomoTec Phase EX460 Upgrade for the 2020 trackday season..... The last time I enyoyed a trackday with the "old" 2018 setup was in October in Mugello, Italy - I improved my laptime from 2:14:95 to 2:13:08 without interim modifications, so the 2nd Lotus season ended perfect. https://www.youtube.com/watch?v=DRvBNN1bjU0 To be continued.....
  3. There is a difference between implied warrenty (consititutes a legal claim within the EU, refers exclusivly to defects already existing when the good was delivered and should not be confused with a legal claim for long lasting reliabilty and quality build) and a voluntary guarantee promise by the manufacturer (usually it is promised that the object of purchase works flawless for a certain time period and all expenses are covered if something malfunctions). The forsaid mentioned Lotus guarantee is the ladder, so they can promise what ever they want and define limiting terms to their liking.
  4. just found that video, somehow depressing..... - but regardless love my KomoTec Lotus Sport 350 impassionate https://www.youtube.com/watch?v=KQhdiDEaHJ0

  6. KomoTex uses a very reliable and obviously significant Dyno called AutoDyn SuperFlow AWD SF-880. If you want to learn more about it you can find it here: https://www.superflow.com/aspx/prodDetail.aspx?prodid=1&catid=1&navid=6 From my point of view against this background the measured values posted above due to the dyno used are most likely not correct (too good to be true...) - disregarding I never heard from a Lotus that provided more power ex works than the manufacturer claimed
  7. I just discovered that the Laptime of the KomoTec EX500 with sequential Gearbox at the Hockenheimring is 1:50 - a sensationel accomplishment! To put that in perspective: the Pole Position for the first race of the Porsche Sports Cup at the Hockenheimring 2018 was obtained by a 991 GT3 with a 1:51:40, the fastest 991 GT3RS accomplished a 1:52:330 Even the Cayman GT4 Clubsport in the Porsche Super Sports Cup on slick tires were not that fast......

  8. KomoTec Close Gear Ratios is highly recommended - remarkable improvement in all gears, not only 5th and 6th. My Exige Sport 350 feels much more powerful. The range of each gear is a little shorter then in the KomoTec graph, e.g. 4th gear goes to 189 - 6th gear hits the rev limiter at 276 which is absolutly fine with me!! The only drawback: significantly more gear box noise I would not recommend the LSD if the profile is 80% road use - I assembled the Drexler LSD concurrent with the Close Ratio and really had to get used to it, in my view the Exige was easier to handle without the LSD. My profile is 85% track / 15% road use
  9. Very interesting remarks from Steffen, thank's for sharing the insight! I just wish that the latest Exige models would perform as well as their specifications indicate and as it certainly feels to drive them. The more expensive a car is, the more important it is to me as a potential buyer that the car is not only fun to drive but actually competitive on track. Given that I can't check that for myself in advance I have to rely on test results BTW: The driver of the Exige (Christian Gebhardt) was the same at both occasions (380 and 410).At least for the Supertest Sport Auto publishes the tested car's measured values for engine power, camber settings etc. to keep the results reliable and transparent. You always know who drove the car and very often the videos of the test-runs are accessible on Youtube - I trust them. The results of the other paticipating cars: Carrera T (1441 kg, 370 PS, manual gearbox): 1:10:3 Jaguar F-Type SVR (1.800kg, 575 PS, FWD, automatic gearbox): 1:11:2 BMW M4 Competition (1635 KG, 450 PS, RWD, automatic gearbox, Cup 2 tires 1:11:9 AMG E 63 S 4matic (2037 KG, 612 PS, FWD, automtic gearbox): 1:11:3 Lotus Exige Sport 410 (1139 KG, 416 PS, RWD, manual gearbox, Cup 2 tires 1:11:5 My conclusion: I will keep my wonderful Exige Sport 350 and will no longer consider to upgrade to an Sport 410 or a Cup 430 - if I need more power I'll go for the EX460 KomoTec kit.
  10. I just read the current issue of Sport Auto and looked forward a comparison where the Exige Sport 410 ran against Carrera T, Jaguar F Type, BMW M4 Competition and the AMG E63S... the outcome is disillusioning - to say the least. Disregarding the price tag, in my view the Exige Sport 410 is almost the perfect Lotus Exige: 416 PS form a chargecooled engine ex works, Nitron Chassis, oil-cooler....., but actually the lap time at the short circuit in Hockenheim is a disappointing 1:11:60, a deep hit considering that a year ago an underexposed Exige Sport 380 (merely 350 PS measured) accomplished a 1:10:80 at least.... I don't believe in automobile conspircy theories...., nobody who loves cars want's to harm Lotus but in every impartial test I read in the last years they failed and did not meet the expectations. KomoTec accomplished an inspiring 2:38 lap time in Spa with their EX 460 this summer, why is Lotus not up to do the same with a company car like the Sport 410? Lotus either should prove their potential reproducible with their own drivers and factory prepared cars at the Nürbrugring, Hockenheim and Spa or leastwise significantly lower their prices - it's nonrational to charge 20.000 Euro more for a car that's 0.8 sec slower than the forerunner at the short circuit in Hockenheim....I'am stunned
  11. I would like to report good news, but regrettably there's no good news as far as my Lotus is concerned..... No spare parts for my damaged gear box available - guaranty in no time denied because of alleged track use - track day in Imola cancelled...., what a dump! Increase in price is obviously the only skill left for now - I hope Geely will teach them a lesson soon! Fortunately I bought my MX5 a few days ago, that's the car that will take us to to Italy next week...... This is what I'am missing due to faulty build quality and to shameful spare parts supply - disgraceful for Lotus: https://www.youtube.com/watch?v=V0X7aJi9ELE
  12. last year I sold my GT4 because I encountered two gearbox failures in six month (both replaced on warranty). Considering that happend with a brand new car with12.000 km, 13 month delivery time and against the background of manifold - partially security-relevant - quality issues with my previously owned 997 GT3.2 I decided to turn away from Porsche and bought my first Lotus. I did not had unrealistic expectations relating to the build quality of a Lotus Exige Sport 350 and so I'am still absolutly happy with my car irrespective the gearbox issues at hand. So my remark was just related to the disproportionate surcharge the Sport 410 costs over the Sport 350 without offering a basically modified and improved drive train. If Porsche would seriously consider to reissue the GT4 with the same notoriously flawed gearbox mentioned above, that GT4 would be unmarketable regardless any increase in power or other modifications that would be offered..... Anyway, regardless the cumulation of EA60 gearbox related issues at my dealers garage that's apparently not a widespread incident at least in the UK which is good news for me!
  13. I suppose that a warranty claim is not enforcable as a plate type Drexler LSD was fitted to my Exige ......
  14. To my knowledge the adapted Toyota EA60 gearbox which is fitted in the Exige 410 is exactly the same gearbox that is used in the Sport 350. Considering that the gearbox in my one year old Sport 350 with just 20.000 km recently failed (3. gear pops out when relaesing the clutch - supposedly a defective shifting claw) and sadly no spare parts are available due to the great number of comparable failures within the last few days (!) at my dealers garage I would not spent the amount of money claimed for the Exige 410 on a car that's not offered with a basically modified and improved drive train Anyway - I desperatly hope for spare parts to come in next week.....
  15. I just want to share the wondrous impacts the berserk pricing policy of Lotus had on me..., apart from a persuading test drive in a 160 PS RWD MX5 with LSD, Bilstein chassis and Recaro seats for 26.000 Euros....
