i just bought an 87, and the ride is very bumpy. i don't know if its the tires or the suspension, or what.

check your tire pressure, and does it have aftermarket suspension

jerd_hambone

the tire pressure was checked today when i bought it. and its all stock. the tires were pumped up to either 15 or 20 pounds of pressure, i'm not sure though.

jerd_hambone

also, how can you tell what model they are? all i know is mine is an 87 non turbo.

wheelbearings might need to be tightened

Icemark

define "very bumpy".

Doe sthe car loose traction over bumps or is it the car rides too firm comparied to what you have driven in before, or you have low profile tires and worn out shocks or what...

But just "very bumpy" could mean 1000 different things.

jerd_hambone

as in when i drive, little bumps seem like huge pot holes. the tires are slightly worn. it does lose traction a little.

Icemark

sounds like worn struts

jerd_hambone

i know it needs new tires, but i don't think it should be that rough of a ride from just tires.

andrewb70

Sounds like you have never had a sports car before.

well other than the fact that it hits small bumps hard enough to almost make it lose control.... sounds like something is wrong.... but thats just to me...

Icemark

yeah that points to worn struts or other worn out suspension parts.

But probably worn out struts

jerd_hambone

yeah... it has the auto adjustable suspension, but i don't think it works.

jerd_hambone

the people that had it before me put rims on it... i don't know if that would make anything different though.

Icemark

what size??? If they are really low profile (such as 17" or 18 " wheels) that too can contribute to bump steer, and poor handling.

jerd_hambone

they are 15's so there shouldn't be lo pro's on it. the tires are very worn though.

therotaryrocket

does it still have the rims on it? did you say 15-20psi of tire pressure, should be like 35 psi. dryrotted or old tires also ride pretty rough.

jerd_hambone

the rims are still there, the tires are about a qyarterinch from being bald..lol

This means it's the factory shocks.. Listen to IceMark I just changed out the shocks on my 86, it turned out they were factory in the front... I could push the shock down with my hand they were so useless. This is probably what it is. You'll want to get some new springs as well, since yours are probably shot from completely supporting the car like mine were.

jerd_hambone

where can i get new shocks/struts, and springs? and about how much will they be?

BlaCkPlaGUE

I'd purchase the ones from speedmachineperformance.com, they have a nice suspension kit for a moderate price.

I've also heard that racing beat makes a suspension kit, I'd look into that first, explore all your options before you buy of course.

I too have the same problem, car is bumpy as hell, I did the manual bounce test and it didn't look to good. Kind of ironic, I want a new suspension set becuase my current one is garbage, but the new one will be for performance and not comfort, the very reason why im buying it

jerd_hambone

i want one for performance, but i also would like to be able to handle driving the car everyday...lol

jerd_hambone

i think its my tires.. they are horrible.... they will only hold 10 psi..... all the rest leaks out.... so if its still rough when i get new tires, i'll buy shocks/struts, and springs....

RSVampire

while we're talking about suspension I was wondering why the Tokico springs lower the front of the car 0.8" and the rear 1.5"!! Why!?

jerd_hambone

to make it sit flat instead of down at an angle.. i think, not sure though...
