You need to do is get your geo checked out.. if you do have neutral toe at the rear like you suggestes it might, it wont be helping.. Also, seriously consider improving your driving style, the binary on/off nature of your throttle application is not helping either. Quick but smooth application is what you need to aim for. Also, by uppin the tyre width you are creating a larger area which needs to be warmed up, maybe having wide tyres is actaully hindering the warm up of them and a smaller width tyre would actually be able to generate heat quicker and offer you more grip Can you get your old and new laps together on youtube and look at the differences between your driving techniques?

Would a rear arb not make it worse? I have the ep 1" front arb and my inside front wheel sometimes lifts off the road. Wouldnt a rear arb do the same to the inside rear?

 

All dependent on the damping rebound rates but In Chris' case probably yes as it won't have been optimised for this. Bars, dampers and springs should be matched to work with each other.

 

I agree that a test day would help but only if you can consistently lap within a few tenths, otherwise it's going to be difficult to isolate the problem.

 

Chris_uk - How dare you suggest that driving style is at fault!

will try and do it now

Chris. Spring rates!

Same as last year

It looks pretty balanced and well setup in the video. It spins a wheel up coming out of slow corners but that's to be expected (even my 1.6 NA does that).

 

If you set it up so that it has maximum rear grip out of slow corners then you'll make it worse elsewhere ie. you'll take grip form the front AND with greater drive you'll generate greater weight transfer over the rear and less on the front - so it'll push into understeer much more quickly and you'll have to get out of the throttle anyway.

 

If you add an LSD it'll also mean you'll push into understeer OR slide the back into oversteer - either way you're not able to break the laws of physics and ask it to take full power out of a slow corner... can't you just feed the throttle in a bit more progressively?

[CHILL Gone DUTCH]

I'm Sure I can but it's difficult on cold tires you have to aggressive. And as some have mentioned I'm not exactly subtle naturally

[The Batman]

im going to try larger front tyres as since fitting the lsd it understeers, hoping this will cure it.

[SteveA]

Where does it understeer? Corner entry, apex, exit, faster corners, slower corners, steady state cornering?

tbh only on the really tight corners lol so to be expected even with wider tyres

Front end is bang on . It's perfect

Sorry Chris, I meant Joe.

As per Captains post your car looks well balanced if you start changing things to solve a heavy right foot you will no doubt upset something else. I'd say tc or softer tyres are your methods of solving low speed mechanical grip issues.

[fiveoclock]

All this talk of spring rates and LSD etc. is all a bit pointless if your contact with the track is inferior. The tyres you have cant possibly be at peak performance on a one lap sprint. Soft compound tyres, standard sizes (195/225) should be your first change. Someone else mentioned it, you could be a bit lighter on the controls!! Soft hands, caress the car round the corners

[CHILL Gone DUTCH]

plenty of role/lean there 

[SteveA]

Roll in low speed corners is not necessarily a bad thing. In testing the other day I found it made me significantly quicker. Differently balanced car though.

[CHILL Gone DUTCH]

just out of curiosity what is considered 

low speed 

medium speed 

and high speed 

 

?? 

[Captain Vimes]

just out of curiosity what is considered  low speed  medium speed  and high speed    ?? 

Ill go for: Low is <50 (hair pins, tight chicanes) High is >90 (Stowe at Silverstone, Riches at Snetterton, coppice at Cadwell..) Medium is everything else
