my lil bro purchased some coilovers . the spring rate on them are 350 and 450 . he has a 91 hatch . wich one's would you guy's recommend go in front and wich one's in the rear ?

 

450 front 350 rear

 

how long has he been driving? 450 in the rear will make it handle better. it also might make him crash.

 

why do you say that it might make him crash if he puts the 450 in the rear ?

 

cuz they are way to big for the rear

 

Which springs go up front?
GC normally designs their spring kits so that the front is stiffer. You can follow that, but ERS(springs) are interchangeable. So you CAN put the stiffer in the rear, it will alter the suspension by basically making the rear stiffer, which makes the car less understeer, which is generally more desirable for better handling performance. However, it *makes the rear stiffer*, and you will feel the difference since FWD cars have the center of gravity more towards the front, so the rear wheels rotate further from the CG than the fronts, thus are more sensitive to bouncing motion. Its up to you. I suggest you just follow what GC recommends, but if you are so inclined, cautiously try to swap them and see what you prefer.

I'd say 450 in the front and 350 in the the back to be safe.

 

what coilover and shocks did your bro get?

 

he just got some cheap ebay coilovers that say tommotorsport.com . that actually arnt bouncy and work well and cant complain about the price either ($45 shipped) .

 

you should get some decent shocks to run with those coilovers..

your going to be underdampened
