Hi all road racers and autocrossers I really need u guys opinion on this. Since I will participate in quite some autocrossing event this year, I am thinking about on getting the SRR 4.7 final gear for my 99 Civic DX hatchback for that(auto-x) and daily driven purpose. At the same time I am getting a Cdn spec Si tranny also.

Not sure if I should install it into my DX tranny or the Si tranny...

For suspension wise I already have TEIN HR coilovers(front 10k and rear 7k), SPOON tower bar and lower arm bar, 15" Kosei K1 Racing and Toyo T1-S.

Any opinion and data will be appreciated, thanks.
