Dropping the car. How Low should I go?




Thanks

Now- I had SERIOUS tire wear issues after I lowered it. The inside of the tire wore a LOT more than the outside, so I HIGHLY RECOMMEND an alignment afterwards. Mine could have been a freak accident, but better safe than sorry.
BEFORE:
AFTER:
It was just enough for me to avoid major scraping. I would have gone lower but my air dams are already touching on a lot of the entrance/exits of dipped parking lots and driveways. I did get an alignment afterwards.
I do agree, if you are using it as a daily driver I would not lower it this low.
If you go as far as the stock bolts allow,you will get about an inch, which is practical, if you want the "slammed" look, I added longer bolts in the rear, and removed the bolts all together in the front. May not be the most practical, but sure looks killer!!! :cool:
But...what everybody seems to forget, we are facing several problems, and that's concerning all of us with lowered C5's.
1) There are NO shortened shocks for our babies available. Why do we need shorter shocks you ask? By lowering the car we moved the "amplitude"or travel area of your internal shock parts up. Instead of riding in the middle section of your tube it rides at the upper limit, even bottoming out and hitting the gas-cap/bump-stop. The result will be that we hit the cap that seperates the oil from the gas in Monotube shocks. Resulting in a premature death due to leakage etc. By then you have to get new shocks, install, repeat. Been there, just done that today.
2) We change the supsensions geometrie. Now, I'm no C5 expert, but it is only natural that when you change all in angles in your suspension, you will end up, even when the car, while sitting on the ground, is perfectly aligned, with performance that is sub stock (only when lowered too far, that is....how low is too low? Dunno....I'm just raising a few points here).
See...we go to Alignements-r-us, the car sits on the lift and the align it for us to our/their specs. But already or now-neutral alignement sits 1 inch or more closer to the fender, meaning further up (excuse me..I'm German and I'm putting up quite the fight to get my English right..and what rhymes is good). Our neutral wheel position already is (compared to the rest of the car.chassis) where it would be when fully compressed. But then we take our C5 out on the road the suspension will be, depending what kind of turn you make, compressed even further exact at that point of time when it is supposed to work the best, when cornering. Not what GM had in mind, especially when it comes to fools like me who removed the front adjustment bolt all together and took more than 2 inches out.
3) The scraping? Best part to get is the skid guard. It is available through some of our vendors here at the forum mall and it rocks! It has small wheels build into a bracket and you will, instead of grinding over, smoothly roll over any obstacle, whatever the speed.
4) I used to work for Bilstein in Germany, only for a short 4 months, but since my family's business is one of their suppliers as well (how do you think I did get that dream-job in the first place, hehehe) I was able to pull some strings and I got them to manufacture....sit tight....PSS9 Coil Overs!!!
I hoooked them up with a southern Cali vette shop and Bilstein in Ennepetal/Germany will add the coil-overs to their to-do list in April!
Don't expect them to be available until the end of the year though.
These will be ( as PSS9 implies) adjustable when it comes to bound/rebound, in 9 steps....unique design when it comes to coil-over shocks for the C5/Z06!!
Cheers,
Goetz
