Hi Green Wing!
Thanks for your reply, now that the weather in Europe is getting better I hope I will get some runs this week. First run with a new car in a new class, it should be an interesting day. By chassis flex, do you mean removing some screws from the top deck? The GRP foams are really great but they wear extremely fast, which is why I don't always use them for training days ( you can buy 2 sets in the morning and after training, qualifications and finals you can throw both sets in the garbage!). The grip level on those foams is unmatchable. I also run VTEC and PMT foams but none are as good as GRP. I like to have same shore front & rear, normally using 35 and 40 in hotter conditions. But, sometimes there are only one type available to buy so we have to drive what is possible at the moment. I believe there is no more Parma on the rims, I will check though

I have tried R9-F but I found that a classic Mazda 6 body is better. I do have a new Audi S5 waiting for painting, can' wait to see how that handles.
