Hi there,
I would recommend using Mardave V54P Tyres on the Rear & JAP 44's Tyres on the Front, as this will give you plenty of Front end grip, without making your Car 'spin out' or 'griproll'..............you'll also find that you'll be able to run full Additive allround. Truing down the Tyres to around 52mm also helps!
I've tried placing some small amounts of Foam under the Rear Pod, but ALWAYS found it to make the Car 'spin out' on high speed corners........I personally would'nt bother with that idea!
The Softer Rear Springs seem to be the best option, but make sure that there not tightened down too far.......have around 1mm droop on the Rear Pod! Also check the Tweak with some Coins, cause if its not set properly, you'll probably find that the Car spins out one way!
Its generally a good idea to Oil or Grease the Front Kingpins, to keep the Front Springs nice & free, as they can sometimes stick, which can cause problems!
I hope that helps
