My 182ff track car build (so far)

[JamesBryan]

630! Wow seems high that doesnt it??

The Cup racers were close to 1000lb rears 👀

 

[Usr117063]

Seems high, going over pebbles shatters your teeth, but everything else its perfect!

 

[JamesBryan]

AST standard track setup is 90N front, 110N rear which is 500lb and 600lb.

That is what AST recommended for me.. But being old my reflexes arent capable of a twitchy rear end so i choose 90/90. But in saying that i have been suffering a little understeer , which after having a conversation with Simon at the Autosports show in January, i've now been experimenting with raising the rear ride height slightly , increased my rear tyre pressure 2 psi above the front, 2 clicks higher on the rear dampers than the front and im pretty happy with the adjustments im making.. The idea of the harder rear is to help keep the weight over the front axle and rotate the rear ,(but you probably already know that) In hindsight i should have trusted AST'S advice and gone with 90/110..

I cant comment on having cold semi slicks on the back but mine is not twitchy at all. The whole car becomes loose near the limit not just the rear or front.. (Private roads)

Granted Im 1060kg half tank of fuel with me edit: 1060+70kg (me)! But I think Im 6-7 clicks from soft on the rears, if I went to 2 clicks say it would be like a boat. Front Im 4 from soft but thats road setting as bumps are no fun after that, Ive set the fronts to max once, darty is an understatement! This is why I want some valve changes done on the fronts..

My car last weighed (last year) was 980kg with half a tank.. So I'm probably roughly the same.. On track I'm now running A048 or R888r ( Track/weather dependent) at 30psi front 32psi rear hot .. 7 clicks front 9 clicks rear.. I find that setup to be very stable and some people say that have followed me that my car looks planted..

Why are your rears higher pressure than your fronts when the rear is lighter?

 

[Eddie555]

Why are your rears higher pressure than your fronts when the rear is lighter?

After taking on board some advise from both Polleysports and Simon, both suggested by running a slighty high pressure on the rear would help my particular situation, as in to help rotate the car and dial out my understeer..

Gets the rear a bit more mobile.

You want it rotating on the limit to kill the understeer.

Exactly this.. and it appears to be working.

Race proven.

In the wet you'll want to revert to a more neutral balance, unless you're a god driver.

Wont your rear tyres over heat in the centres?

Behave.

Camber and toe will also effect the way the tyre heats up mate. You need a tyre probe to monitor temps to tweak the setup properly. 👍🏻

Sorry dad, I was thinking about next trackday I'm going to take the thermal laser from work with me so I can see what the crack is.

In the wet ive been dialing everything down to as soft as poss with the emphasis of getting more grip to the arse end..

IR thermometer will only tell you surface temps.

I use the Longacre pyrometer, it's not cheap but it gives accurate temps quick.

Yeah that's the way to go mate.

You need compliance in the wet.

Gives you an idea though doesnt it

If you pull in off a hot lap yeah it will roughly.

After a cool down, you may as well be guessing tbh.

Toyo R1R

I've been using Uniroyal RS3.. And they seem to be quite good as long as there is standing water. As soon as a dry line appears they overheat really quickly. I just pull in and swap to R888r on those damp days.

What do you think to them. They are pricey arent they?

 

[Eddie555]

Ilya (pule333) ran yoko A052 last time we were out at Bedford in the torrential rain and they seemed alright.. Although he did drive my car with RS3 on and said my car felt more stable than his..

Well no they're not.. But I was at Brands on a very wet day and some honda drivers that race in a Tintop series were using them and said how good they were in the wet, so thats why Ilya tried them. TBF they weren't bad.. You know his car and how mental Ilya is and he was doing ok on them..

Not as good as Rainsports on the absolute wet, but then they're better in drying conditions.

Around £70 ish a tyre I think.
