I heard that Andy of Saturn had uprated his rear springs from the book from 200 per spring to 250 to help stop a bit of roll.. When I had a go at
Blyton I kept going progressively harder on the dampers under order from the instructor, to the stage when I took it back on the road it was hard as
hell when I hit any bumps.
I would suggest that if really for track only look at anti roll bars front and rear or torsion bars what ever they are called.
Dampers I believe will not really help on roll so think the bars would help the most.
Please bear in mind I am not a track expert so could be talking bull.
Are you close to any race companies you could try like procom etc.
Adrian
Why do I have to make the tools to finish the job? More time then money.

thanks for the reply, ive been looking into anti roll bars , its purely for track so i dont need it to work on the road, i was also thinking of
changing the springs but not sure what to start with. I would take it in to get it sorted by a specialist but im out in France!

I would copy the spring rates that are MK track cars for now. When you get back get yourself to procomp. Amazing value for money.
Personally I look at the locost and RGB racers for inspiration. I don't think any of them are using anti roll bars with a marked success. I
would suggest springs and shocks need dialing in.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

I'd say stiffer springs not anti roll bars too. Anti roll bars allow you to use softer springs for a better ride on the road while still
controlling roll in the bends. Better to get the balance / roll right with the spring rates IMHO.

I will take alook at springs then first. whats best do you guys think,go up in 50lbs at a time or should i go for more?
The moment i go into a corner it starts to roll and completey breaks traction,not very fun!!
Cheers

Save your money buying loads of pairs of springs and go see a professional like procomp. It will be far cheaper in the long run.

Even if you just call Procomp, they will certainly put you in the right direction.
