^^ agreed. ive spun the fof severeal times (still learning,doh!!) i dint think i'll be putting r comps on it till i ca nrun a lapping day with my autocross group and not spin out like a fool,lol.
as for what type of power adder. i say turbo. it's the most flexible and can be lowered or raised depending on the size of the track and turns. my gues is 8.5 to 12 lbs. will do it for you.
your car will never be like my car, after all you have common sense......
