Hypothetical upgrades

Recommended Posts

Guys, I've got the time to get the car on track a reasonable amount over the next couple of years, and am investing in some training.

Hypothetically speaking (obviously!), what would be the most effective upgrades:

Geometry

Pads / fluid

Tyres

Wheels

Suspension

The car is a 350 sport on standard wheels and tyres, although I believe it has 2 piece brakes.

Thanks

Gareth

Upgrade today to remove Google ads and support TLF.

Subsequent you find the upgrades I carried out with my Sport 350 - the car was bought new in February last year from KomoTec in Germany and all upgrades were performed there

  • KoBra 4 brakes and PFC  pads
  • fuel cell 60 ltr
  • Ohlins suspension kit "track"
  • transmission oil cooler kit
  • close ratio final drive
  • LSD Drexler
  • 4 point harness
  • harness bar
  • towing eye
  • forged wheel with Trofeo R

My Lotus is the perfect car for trackdays and fun on the street at any speed - the best car I ever owned!

Every upgrade is recommended - if my Lotus would be stolen I would get myself a new 350 Sport and do all upgrades again with KomoTec

4 point harness was the single biggest difference for me. It makes a big difference being strapped in rather than hanging on.

This. Makes a huge difference and low cost.

The boring but correct answer is driver coaching. The difference between a novice and a pro around Silverstone can never be made up by mods. My own laptimes at Goodwood tumbled in the same bone stock car after tuition and more circuit knowledge. Probably something like 15 seconds difference between my first attempt at a fast lap and my personal best.

Beyond that, I’d say tyres will make the biggest single difference on a 350 but obviously only when the conditions are right for the tyre. Pirelli Corsas are a good all rounder but a Trofeo, Avon ZZR or Michelin Cup2 is a big step up if you keep them at the target pressures of 2 bar hot. Keep them at the recommended road pressures and you won’t know what the fuss is about. When they ‘switch on’ you’ll know it. The price is poor performance in heavy rain, cold weather (they don’t even liked being stored below 10C!) and they won’t last as long. Well worth it though.

The 2 piece brakes are very strong. You’ll have to be really working them hard to find them wanting. Dampers are said to be worth quite a bit of laptime at Hethel, many advantages to an adjustable set up too. Of course you get compound benefits with better tyres and better dampers bringing the best out in each other. Both will improve your braking performance and traction too. Any true Lotus man should look at weight loss before power increase but banzai power is undeniable fun but it can delay your development as a driver. When it’s easy to make up for lost time on the straights you don’t have to try so  hard in the corners.

Fun is the name of the game though and you’ve got a head start with a Sport 350 in the garage.

LSD if you want to go round corners sideways (this could just be me?)

Thanks, good call on the harnesses, just realised I don't have a towing eye either,  any advice on who I should speak to about these?

thanks

Towing eye will be available from your Lotus dealer and the front grill will probably need cutting (at least it did on the V6S) and the number plate lowering slightly as it may be in the way in it's standard position.

With harnesses I bought these https://www.seriouslylotus.com/schroth-lotus-ii-fe-4pt-asm-push-button plus you'll need a harness bar. A Lotus dealer or specialist should be able to fit them for you.
