eBay lowering bolts?

[seppi]

Anyone lower there c4 with longer bolts? Curious as to how it handles. I’d like to loose some gap in the rear. Any thoughts?

Lose lol

it will look cooler but there's too many speed humps

Bouncy?

Bouncy?

I think he might be thinking more like bottoming out or scraping problems. Not sure about Ontario but we have some wicked traffic calming speed bumps and humps here in Alberta... Especially in parking lots and residential subdivisions... The air dams regularly scuff them but you'd likely be paying pretty close attention if she was lowered...

Ya we definitely have those puppy’s lol. I’m only thinking an inch and a half in the rear only

Half of the gap maybe

I lowered my C5 on the stock bolts. I bought longer ones, but I really would not want to go lower than what the stock ones offer. It was a spur of the moment lowering so I never did take before/after pics.

I'll only add this as I'm sure the results will be the same. The car does pretty good, but does bounce off the bump stops more than it used to. Actually, it never would hit the bump stops so that shows it wasn't using all the suspension. It seemed to firm up the ride, which doesn't make too much sense as the springs are in the same position, just the a-arms moved. Maybe the change where the piston sits in the shock firmed them up???

Anyway, next summer, I'm going to cut a bit of the front bushing to get the front to sit down a bit more, than remove about half the bump stop from the shock to allow a little more travel (~1/2"). From what I've read, this is just enough to keep from bottoming out the suspension. The next step would be to install coil overs. $$$$$

I would say to try lowering on the stock bolts, if it's the same set up as the C5. See where that gets you, then if not enough, just by some Grade 8 bolts in the correct size.

I recall Manny's note here when he first got his C7 Z06. To lower the car he used dropped spindles that accomplished the "visual" part of the modification but still allowed the suspension to remain fully intact in terms of function and travel. Now this would only work on the front I guess but maybe might be another alternative.
