  1. to be honest, I'am disappointed by the Emira. Looks good, but

    • low weight as former essential Lotus feature with 1.400 kg transformed to the contrary
    • assisted stearing (at least hydraulic)
    • V6 still with the outdated manual gearbox and not available with DSG  

    After all it's calming that all the KomoTec power upgrade options can still be applied. I expect the aerodynamic drag to be mch lower than with the Exige (0,45) and therefore I'am curious how the Emira will perform on track.

  2. I look forward the new Lotus Emira - for sure it will  be an amazing car. Lotus ended 3 model ranges to be replaced with with just 1 new model - they are not suicidal, it will be a great car for sure.

    I for one hope that my wonderful Lotus Exige EX460 Vivid Green will be with me for many years (and trackdays) to come and that there will be no necessity to replace it with an Emira.

  3. I ordered my Final Edition Exige in Vivid Green last year and while I still don't regret the timing of my order in the face of the Exige 390 I have to admit that the Exige 390 is a tempting offer that would have saved me a few Euros....

    The Exige 390 is offered with the watercooled chargecooler - certainly that is the most important feature. I would have upgraded to the KomoTec EX460 anyway but that upgrade would have been 6 TE less expensive than applying that upgrade to the Exige 350...

    BTW: The clutch of the Exige 390 is not upgrated and there's no oil cooler included but there's a digital AIM display which is great!!

    I got the MX2 Strada from KomoTec which works perfectly with the AIM Smartycam HD - I seriously doubt that the OEM digital display offers that kind of compatibility.

    Concluding: The Exige 390 is a great offer with a nice stearing wheel and if you could order it in Vivid Green (?) it would be almost perfect disregarding the rear lights.....

  4. In my first Exige Sport 350 I pondered between the "Close Ratio" and the "EX460- Kit" - given that I had bad experience with modifications at the exhaust line with a Porsche I previously owned I decided for the "Close ratio" option.

    Downside: apart from the expense there is noticiable increased gearbox noise

    Benefit: sunstantially better torque and speedup, car feels much stronger and agile, not only in 5. und 6. gear.

    BTW: the gear range from my perspective is not perfect for track use (3. gear - 146km (154),  4. gear - 187km (202)

    Here you can see the (limited) advantage compared to an equally powered Exige without "Close ratio" gearbox


    In my new Lotus Exige Sport 350 I decided for the EX460 Kit and against the Close ratio - without power upgrade I would have installed the "Close ratio" again.

  5. When I saw the JUBU Promo-Videos for the first time I was tempted, so I reflected the issue- but after aa while I decided basically against it, not only for the matter of price (which from my point of view is ridicilous...).

    • I love my Lotus for what it is, so there's no need for more gearbox-comfort on B-roads.
    • Seeking better performance on the track, I would opt for the KomoTec sequential Gearbox with paddles - durable and heat-resistant on track which I do not expect for the 7 gear DSG VW solution.

    In spring 2021 hopefully I will testdrive the supposedly 6 gear KomoTec DSG solution - I'am really curious and look forward the test drive, but I'am sure I will not change my mind.....

  6. In August I drove my new Sport 350 EX460 Vivid Green Lotus first time in Zandvoort at 36° and unfortunately two times the water temperature exceeded 100° and I had to take a break.... (no harm done)

    I was advised to switch off the AC which helped to keep the water temperature at 96° - good advice but a sweaty experience.....

    So, preparing my Lotus for the 2021 trackday season two weeks ago KomoTec assembled the bigger radiator - I hope I'll help to keep the water temperature below 100° under any condition....

    Additional they assembled the "Uniball Upright-Bushing-Kit „KT-Track“ -

  7. Yes, I did - but please keep in mind that my modifications are based on a 90% track use profile...

    Chassis: Nitron 46 2-way (great for track use but very noisy at low speed on B-roads, for street use I would recommend the very good and low-noise Ohlins "road and track" chassis)

    Transmission Oilcooler (track)

    Quaife LSD (track)

    KoBra 4-4 brakes (track - for road use maybe just the front axle if at all...)

    Forged wheels (track and street - just looks great and feels better)

    Exige Sport 350, EX460, Ohlins Road and track chassis. forged wheels - nothing left to be desired!!



  8. If you consider a power upgrade go for the EX460 with the watercooled chargecooler - otherwise I recommend the close gear ratio over an upgrade prone to heat soak like the phase EX430 or smaller

    Apart from that: I would always choose KomoTec, they are the benchmark and their solutions are proven reliable


  9. I use this mount which provides a firm connection with the bulky slats of the Lotus ventialtion nozzle

    In addition I use this USB adapter which makes it much more comfortable to attach the charging cable when needed.

  10. I bought the spacers at KomoTec, although the spacers apparently are not offered in the shop.

    The spacers come with extended Lotus wheel bolts - the set was sold for 129 Euro. 5 mm each side was the smallest available size. BTW: I'am still exited about the Vivid Grenn every time I see may car, it's just perfect!!

  11. The gearbox oilcooler is applied, but even so the gearchange from 3 to 4th gear was far from perfect to say the least..., KomoTec ventilated the 240 mm sport clutch, but I doubt that the real cause of these problems is identfied yet...

    The noise you can hear at 7:38 was very disturbing to me and sounded much worse in real than you can hear it in the video - given that repeated breaking from 250 to 50 calls for dependability of all parts it was an annoying fault that unfortunately could not be located on the spot by the KomoTec mechanics.

    A few days later the car was checked by KomoTec in Mendig and it turned out that the rear wheels have touched the inside wheel-house plastic-casing on that bumpy part of the track under heavy breaking - I guess that's due to the adjustment of the Nitron 2way chassis...

    The suggested solution: I will fit 5mm spacers at the rear next time on the track (02.08. Hockenheim again...) and hopefully the spacers will fix the problem.
