Lowering a ZR-1 questions...

So what's the big deal?

Lowering?

I lower mine every time I get into it.................................

It could be possible to lose traction on all four at the same time while slamming the tub to the pavement. Any one know the measurement?

Good point Steve. However, I don't think that lowering the car would affect where the bump stops are. You are just taking up an inch (if you lower it that much) of the suspension travel.

Something to think about though because my tech speed at SORC is 140 mph and there are about three stretches on a "not so smooth" road where I am hitting that.

Sometimes I think "just leave the suspension alone". ZR-1's ride a little high which is a trademark of the car and on my stock Z's, I wouldn't think about lowering. It's just that you know....mod "itis"... I added a little power, now why don't lower it a little, and on and on.

Unless you are a track rat, lowering the car a full inch all around will come with some compromises.

Trying to go fast on windy roads which have a lot of bumps, heaves and undulations, you're going to be tagging the bump stops.

When that happens, the wheel rates go sky high and the changing wheel rates make the car very difficult to drive at the limit.

Also, just cruising on the highway, if the road is rough or has a lot of dips, swales and heaves, the ride gets really choppy because your tagging the bump stops sometimes in the tour mode.

Thanks Hib. It is this kind of feedback that I welcome.

At SORC a few weeks ago, there are a few long stretches where I was reveling in my legal "authorization" to be going 140 mph. If you had ever raced there on the road we run, you would know it is a recipe of "bumps, heaves, and undulations"...seriously! It only gets relatively smooth at speed!

I will tip my hat to the Scott Allman, John Heinricy, and others of the C4's past and think I will leave my ride height alone.

Moracca valving with a lowered height would probably work, but I kind of like my quality.

Hib, in doing my research, I was wishing I could ask you if you had lowered Barney. The one picture I always see of you negotiating a curve makes it look like it is lowered. Your suspension was probably just "compressed"!

Thanks.

Practically with two passengers, a yorkie and luggage for a week and carving the mountains the safest is to have all the suspension travel you can get. Best to leave the lowering for the show and the track.
