Thought I would show a couple pics of the new coil over kit installed on my car.



I'll be sending a couple kits out for testing this week.

One kit is going on a 510 rwhp 6-speed car and the other is going on a 800+ turbo charged automotic car that is flirting with 9 second 1/4 times.



The upper bracket has 3 height positions.

The coil over has about 4"' of adjustment so there will be lots of adjustment a person can do for ride height.



I really excited about this coil over kit. I think it's going to make a huge difference for the tuning of the GTO suspension.

The double adjustable coil overs will allow you to adjust the squat (compression) and also the rise after the launch (rebound)



These photo's were taken on my lift. It doesn’t look like there is any room between the tire and the spring but when you put the car on the ground the angle changes and there is plenty of room.

Here are photo's of the car on the ground.

The kit is $899. and comes with double adjustable QA1 coil overs & springs plus all mounting hardware.
It's a bolt on kit. All you have to do is drill one hole down through the trunk on each side.
I'll have a full installation write up soon.

Thanks
Chris

Does this significantly increase the amount of tire that can fit inside the wheel well? My min issue right now is the shock-rub....If so this could be HUGE

No, the coil over kit wont give you any more room but we do have a few products that will help in that area.
We have billet shock extensions to get a little more room between the tire and shock.

And I also have modified control arms that when used with a mini tub you can get a whole bunch more room.

The tires I have on the car in those photo's are 29-14.5 Hoosiers.
What I did to get those tires under it and keep the IRS is our modified control arms, mini tubs and coil over kit.
When you do a mini tub this big you about have to go to coil overs.

Thanks

Thanks for the links, I may try the shock spacers....I have zero interest in mini-tubbing the car. If you have any other good advice for a setup without mini-tubbing, please shoot me a PM.

Thanks,
