Lowered on coilovers - concern with noises?

[KBBoss302]

I have KW V3 coilovers and, although not slammed, it sits quite a bit lower than OE (lower about 1.25" front and 1.5" rear). When I am driving it in a rather, ahem, "spirited" manner and hit some big bumps I hear some pretty good clunks and clangs. I spaced my panhard brace down about 3/8" and I am not seeing anything hitting/scratching/scraping under the car so I can only assume that it is the over axle pipes and bump stops making the noises.

For those of you running lower springs or coilovers, what other things should I be looking for? Am I worried for nothing? I will probably crank the ride height back up another 1/4-1/2" to try to alleviate the noises. I never had any such noises on Ford Racing P springs, by the way. And yes, I have trimmed my bumpstops.

Thank you in advance for your comments.

KW uses polyurethane bushings for the rear shocks (on the top). They are too short and often lead to noises in the back. Jack up the car and look at the top of the shock from under the car, you will see the gap above the bushing. You can swap the bushings off your stock shocks to eliminate the noise.

Thank you for that information - I was wondering about that gap myself when I installed them and that makes perfect sense.

Just so that I am clear, is this the bushing/insulator that you recommend swapping back in?

That is just the upper half of the bushing, sold with the nut. The lower portion is sold with the shock. If you still have your old shocks, you can transfer them. Otherwise, check with a local shop. Most shops (like mine) keep "spares" around, lol.

Good luck, let us know if this fixed the noise!

Hey Tim - it just dawned on me who you are - you actually installed a driveshaft on my black Boss a few months ago ("in the pumpkin patch" confused me!). Thank you very much for the replies! I will swing by some time and see if you have those spares since I sold my OE shocks.

Thank you!

Update: it was my Bob's axle overflow reservoir setup. I was running it off the driver's side axle hole and it was smacking the exhaust, so much so that it actually cracked the fitting. When I first got the kit, I tried installing the fitting on the top of the diff, but there wasn't enough clearance between the fitting on the top of the diff and the reservoir itself which led to me position it on the axle.

I may go back to the ineffective turkey baster or maybe try the JLT setup which only mounts on one side of the UCA.
