Setup Help

[lotusmark2]

Hi
I am running a MR4TC (origional) with front and rear raoll bars and a front one way diff and I am running on a tight and twisty tarmac track with one straight that has a 90 degree turn at the end.
My problem is that I cant seem to find any rear grip and stability.
The car turns in very sharply and the rear is all over the place.
Does anyone have any setup ideas??
Cheers
Mark

hi mark i use to have your same problem what i did was 1. placed the rear w-bones to the top pin position to add centre of gravity 2, mountes yokomo silver springs, 3 mounted shocks at far top hole and filled with 40compound oil , what about tyries? what are you using!!!!!!!!

try 2 deg of toe on the rear
I could never get mine to handle as standard ,untill i started using the 1 degree rear blocks (car has 1 degree built in ) giving 2 degrees

Thanks for your input guys.
things have changed a bit in the last week or so as I have now changed from the standard chassis and tunnel config to a custom carbon fibre flat chassis and top deck.
The results so far are very good and it is a lot more responsive however I think I will get those 1 deg toe in blocks to made it a little less twitchy on the back, what do you think?

Just ordered the 2 deg rear replacment hub carriers so fingers crossed..

Its been a long time since i run my special
But im sure the car has i degree toe in on the wishbone mounts
so a 0 deg block gives 1degree
a 1 deg block gives 2 degrees
and so on so your new block would give you 3 degrees
that would definately tame the rear but might be a bit much

[lotusmark2]

What would be the result of to much toe in?
scrubing tyres, reluctant to turn in?

+slow down the straight

well I'll give them a go and if they are over the top then I'll get a set of 1 degree hubs, they are only £12 including bearing.
