Road Course supension help needed 01 vert

[LWM]

As the subject implies.

Car is an 01 Convertible LS1.

Has a 6 Point roll bar welded in.
Has Bilstein shocks.
Has Strano 35mm front and 22mm rear sway bars.
Has KBDD subframe connectors.
Has Wilwood 6 piston brakes up front.

It is still quite rolly polly in the corners. I know its a heavy pig of a car, but it sure is fun.

I'm wondering if anyone has gone further in the suspension department and what they did and what worked, how well ... etc.

thx

'Wray MacKenzie' is that you? If so have you sold the LT1? I imagine you are going to run at RCMP?

Anyways I have taken the suspension mods farther as seen in this thread:

It is still soft in the corners beacuse you are on stock springs and stock rubber bushings imo. You have plenty of bar (front and back) for RCMP.

I really like the rod ends for bushings on a road course you could consider switching out upper/lower front/rear A-arms PHB, etc.

The Bilstiens you have are not adjustable and a better choice for road racing is Koni's for sure.

Lastly of course is the springs. A better (stiffer) spring will do wonders for the way our cars handle.

IDK what the regs are for your racing bracket but... Some lowering springs will work wonders for the nosedives, rolls, etc. Don't forget LCA relocation brackets, and an adj. panhard rod. In addition to being a little stiffer with progressive rates, they also lower your center of gravity which helps you maintain more balanced weight ratio in your corners, etc.

Yup, that's me.

Stock springs and bushings ... yup. I tried a set of Eibach springs (Sport line +/- 1.3" lowering) ... OMFG what a disaster, bottoming out in the rear within 3 blocks, had them removed the very next day ... (bad taste in mouth).

I read that the KONI SAs will give about 3/4" drop in the front if set on the lower perch, not sure how that is accomplished ... details?

Considering my experience with the lowering springs, are there any other spring options out there that might stiffen up the car a little, but not make it unlivable??

And the LT-1 is still for sale, but it is a hard sell, who in their right mind wants a 600hp grocery getter?

thx

Maybe you can part out the goodies and return her back to stock? Could mean that I am ready to get blown?

I am so glad you said that about the Eibach's. Everyone for the USA will not belive the road conditions we have to live with and as a result (aswell as running 315's) I used 1LE springs which are much stiffer but at the same/stock height.

I have SA's and there is two lines/indents on these types of shocks alone. You can move the spring perches to the lower one to get a 3/4" drop in the front but I used the stock height one and with the aftermarket arms I was able to get the alignment numbers I wanted when I set the goals for my suspension project without the drop (an therefore) unlivable road manners on the street.

She is stiff but not bone jarring with any bumpstop contact at all.

You going to come down to SWM here in 'lil LA this weekend? You will not regret it and it might give us a chance to finally talk in person.

-BMR Panhard rod...adjustable
-has corvette rotors and calipers...slotted and dimpled rotors
-no need for drilled...theyll just get destroyed
-im running on goodyear Eagle F1's...they destroy the road upon which they ride

Koni SA help alot, and im waitin for Stranos lowerin springs. Weight reduction and balancing the weight of the car helps loads too.
light weight wheels and racin seats are good.

I've run similar setup for awhile.
then went w/ koni's + prokits, then coil-overs.
Wouldn't worry too much about tipping over, unless you end up going sideways outside the asphalted area (grass sideways = bad) especially if wet.

Convertibles are heavy, and with extra weight, such as rollbar, sfc, 9", etc, it does add up.
I wish my weight would be under 4000lbs.
from what you mentionned, you didn't say anything about the differential... is it the stock 10-bolt ?
if so, I'd look into a T2R... and you'll really get some gains out of it.
