weight, wheel offset, ride height, CG and RC, I guess it's fine to use what someone else did as a base line but coil overs can get expensive if you don't get the right ones especialy for a road and track application that should use da shocks.
real race cars are not driven on the street, but to answer the question there are a lot of "race" shocks, Penske, Afco, Pro, Koni, Ohlins, Bilstein....
