rear has two options in suspension
all coilover with seperate spring matched to front spring = cost range 2.5lakh to 3.5 lakh pkr , ultimate circuit track car suspension. rear has coilover and spring in relevant slots not like fwd coilover
2nd option after markt performance spring.(i have one in box) and gas shocks tokiko , kyb etc.
i used my kyb in starlet, starlet kp has same rear suspnsion fitting as ke or ae, spring is in box as shown above.
front has spindle fitted to coilover, rwd car ke should have 4 bolt in spindle same ae86. starlet has 3 bolt in spindle so my coilover didnt fit on kp. its ( the workhorse type of car) and stock suspension in good condition.
weight shift driving is better with full foot of tyre using negative camber
