Beagler Posted March 18, 2023 Share Posted March 18, 2023 So the 2019 Sigma 270s has had a 310 engine and the brake upgrade to 4 pots and M/C so what would you do to improve performance. Link to comment Share on other sites More sharing options...

Andy135 Posted March 18, 2023 Share Posted March 18, 2023 +1 to #2. Improve the driver before improving the car. Link to comment Share on other sites More sharing options...
Dan R Posted March 18, 2023 Share Posted March 18, 2023 I think the world is your oyster when it comes to upgrading,..... assuming you are already skilled enough to extract all the performance from what you have at the moment, otherwise you are just carrying around more excess potential that cant be used Link to comment Share on other sites More sharing options...

TomB Posted March 19, 2023 Share Posted March 19, 2023 Tyres are a quick & cost effective upgrade. No point having loads of power and big brakes if you can't use them due to rubbish tyres. Link to comment Share on other sites More sharing options...

ScottR400D Posted March 19, 2023 Share Posted March 19, 2023 Decat pipe? Link to comment Share on other sites More sharing options...
Beagler Posted March 19, 2023 Author Share Posted March 19, 2023 Dont want to Decat as I would have to inform insurance and wish to stay legal. I dont have an issue with driving a faster car as I have ridden 1200cc motorcycles for years that do 0 to 60 in 3 secs. I have also driven faster cars than mine. Thanks to those who gave helpful advice. Link to comment Share on other sites More sharing options...
ScottR400D Posted March 19, 2023 Share Posted March 19, 2023 I doubt your insurer would mind if they were OK with all your brake mods. Link to comment Share on other sites More sharing options...

Beagler Posted March 19, 2023 Author Share Posted March 19, 2023 You reminder is completely superfluous. I have modified or upgraded many vehicles in my time and always with the knowledge of my insurer. This car is no exception also this was a CC factory built car. I would be surprised if my insurer would be happy to continue covering a car that contravenes emission laws contributes to atmospheric pollution.

Toby S Posted March 20, 2023 Share Posted March 20, 2023 Tyres - Toyo R888R's are pretty good -205/60 R13 on rears, 185/60 R13 on the frontAdjustable platforms - Protech are reasonable priced optionsCorner weightingAero or Brookland screens - feels like you're going 20mph faster Link to comment Share on other sites More sharing options...
krisfl Posted March 20, 2023 Share Posted March 20, 2023 Agree with Toby above. But I'd add 13x6... front and rear (my preferred tyre is the Avon ZZS for road and track) I wouldn't go to wider on the rear until you go north of 175bhp. The car is much more nibble on narrower rears. And doesn't need the extra grip with a stock 310 engine. Especially if you have or fit an LSD Adjustable suspension collars a must before flat floor as suggested above Rear anti roll bar is you don't have onethen corner weight/flat floor as Toby suggests after that:-Tracsport LSDultralight flywheel and clutch ( via Premier Power) set that sigma free! F160/F175/F190 from premier power... transformational... Link to comment Share on other sites More sharing options...

Leadership Team Toughie Posted March 21, 2023 Leadership Team Share Posted March 21, 2023 Back in 2016 I did a Get To Know Your 7 day down at Gatwick, with Caterham's Simon Lambert.While the Club's 3,000 members will have 6,328 views about the right thing to do (I'm too ignorant to have a view), here's Simon Lambert's list from back then:- 13” wheels. Feels much more 'planted'.ZZS tryres. Better in wet and more progressive (also ZZR).4 point harness, correctly worn (tight to breathe). Better connected to car. (Schroth harness if you’re thin). The tighter you're tied in, the faster you drive.Rear anti-roll bar (already got a front one) £150. Take off in wet. A softer car is quicker in wet. Orange is basic ½”. Red is 5/82, so a bit stiffer.LSD. Especially in 160 – 170 bhp.Brakes. Big brakes on front. Bigger master cylinder.Then you can start upgrading the engine Link to comment Share on other sites More sharing options...
