Hey guys, I wanna lower my 88 IROC a bit. I think the storyline springs are the perfect drop and I'd loke to get them... I have a quick question.. Do I need to run caster camber plates or any other suspension components with these springs? I'm on a budget and I dont really want to change a lot of suspension parts. Thanks

 

May need raised strut mounts.

 

Yeah? I only ask because I was reading the " lowering 101" thread and it explained that when you lower one of these cars you'll also need a different tourqe arm and all this other crap I don't want...

 

You don't need a different torque arm.

You WILL need LCARBs to correct the already-defective geometry these cars were born with, which lowering whacks out even further. SOOOOOPER expensive item. Prolly close to $75. Check the board sponsors, several of em make em.

 

School me on the LCARBs.... I've never heard of them..

 

Look at the rear control arms.

Here's a real crappy pic.



Ideally, you want the rear axle and of them, to be slightly lower than the "frame" end. About ½ - ¾" is about right. If the axle end is higher than the body end, the car will most likely have wheel hop. Obviously, since lowering lowers the body while the axle stays at the same height (sitting on the ground), doing that automatically makes the problem worse.

You can see (to the limited extent you can see anything at all) the brackets in that pic. They just sort of extend the stock bracket downwards. Very simple. VERY effective.

 

Ok,cool. Butnim surprised there's nothing I need to do in the fromt to correct for the lowering springs.

 

As said, maybe strut mounts; outside chance also, bump steer kit. Depends on how perfectly you expect the car to handle.

There might be a few other minor tweeeeeks you could do. Sway bar end links for example. You can see in my pic there, the ones I have on it, are too long. But since you'll be renewing those anyway as part of your whole package, all ya gotta do is, when you buy em, pick out some that are different length from whatever you have now, to fine-tune them.

 

You will need to get an alignment done to correct the camber change.
An adjustable panhard bar in the back will correctly center the rear end. The lower control arm relocation brackets really should be used with the lowering springs.

Founders seems to cost the least and the quality seems as good as any others.
