here is the size comparison between stock & buddy club, for coilovers, size matters... it really matter for shocks. bigger the casing, more fluid capacity, like engine oil, more hydraulic fluid = cooler shocks = less chance to get overheating = no need to upgrade to stiffer spring rate to "band-aid" the problem. available at www.fkxracing.com
one of my favorite datalog from @simple_eefg4... this is an actual data from drag racing... you can see during his 1320 run, the ect stay at consistent 175°, the iat drop very fast after launching due to ram air intake. and factory 4.7 final drive is almost perfect for drag racing.
