Anybody know if the stock height adjustment bolts can be purchased without buying the whole spring.

RicK T

No. I found that out last Fall:

There is always a junkyard for used parts.

SUB VETTE

Have you used either of these? and what's the verdict? I understand that Delrin has no cushioning effect.

First I cut the stock bolts, then I bought aftermarket lowering bolts.

My experience was so bad with aftermarket lowering bolts I bought coil-overs. It took me two years of listing in the for sale section to finally get the OE bolts to put back into my springs in case I want to remove the coil-overs..

Tim, you still have those old OEM lowering bolts?

I like to do some R&D with UHMW and different grade of Delrin I have laying around. Need to know the naked dimension and physical attribute of the OEM lowering bolt without the rubber bushing.

timd38

Sorry gone.

^^^Not an issue!

I got both high grade UHMW & Delrin laying around. When I decided to change them out, just need to put the car up on stands, remove/strip rubber then make them up to suite. Set up will be the same for 1 or 2 sets, most likely will have round/radius end shape, better to follow arc movement of control arms, make them out of two different materials, try one then the other and decide which for keeps. Endless stimulating project helps keep brain storming juice flowing.

I have a set of hardbar/vansteel bolts, but have been holding off the install until I can get the car corner balanced at a local race shop

From what Ive read on this site you need to make sure the spring contact points on the control arms are cleaned up/polished to ensure theres no binding, but other than that there shouldnt be any issues

SUB VETTE

Thanks for your feedback. Anybody else have experience with the hardbar bolts?

victorf

As found on mine, there is no direct spring contact points, but contact area under OEM rubber bushing on control arm was lapped smooth with road grits after 28 K miles. As an temporary aid, I put a layer of graphite powder on contact point after vacuum up miles of accumulated dust, sand, grit and pebble before reinstallation of subframe assembly.

Road grit will always be a problem. With given exposure condition, not so much with the attaching bolt grade, actual contact/cushion material choice is paramount and will certainly be a compromise to a certain degree.

Interesting but relatively, a simple project for those having the resource/capability for sure.

Victor: Thanks for your insight and tips. When you finish your project and put it back together a photo would be good.

Get on the phone to the local junkyard. Somebody must have a total with a broken spring that they will sell the bolts from.

Contact me off line. I just replaced the rear spring (cracked) and would part with it and/or the adjustment bolts/pads. You only pay for shipping.

Does anyone know the proper procedure to adjust the Spring Pad/Adjuster, ride height?

4 corner balancing.

Short of that, all you can do is get the car on flat ground, and break out a tape to measure from the ground to the fenders to get you in the ball park of 4 corner balancing instead.

SUB VETTE

email sent. Had my car 4 corner balanced at excelsiormotorsports.com in Escondido. Great job if you want to drive over there.

haljensen

The 4 corner balance has NOTHING to do with measuring the height. It's adjusting the height to get balanced weight on the corners.

If you want the best handling then have the car corner balanced.

If you just want to lower the car for appearance then measure to the fender lip and adjust for apperance.

victorf

"4 corner balancing." What? Where is the source your statement is based? Or is it just another one of your many posting, that are based on what you think you know?
