Ive got 2 HR31s myself...ones a Standard coupe GTS-X RB20det lsd (but replaced with locked atm)active front spoiler etc. and a auto rb20e pillarless for my daily. they are solid cars the 31s. easy to get power out but jap specs parts are harder to find compaired to auzzys.but jap specs are staunch. btw they are irs so can have some serious camber goodness...-offset ftw (just need to get rid of xxr for some 15x10 xr4s now lol)
