I want to lower via drop spindles so I don't have worry about any correction kits or adjustments, at least for the front.

When I first installed the springs I just did an alignment - no probs. BTW, I also installed new isolators front and rear when I installed the springs. Approx 6 months to a year later I installed an adjustable panhard and relocation brackets (Spohn on both). The car was fine without but you will lose some traction without the LCARB and the axle pushes out a bit with the lowering and that is corrected with the panhard adjustment.
This took my car right where I wanted it.
Other shots....

The entire suspension has been upgraded with the exception of the Relocation Brackets. Which I would like to do in the near future.
I have all the specifics on the web.

Just reading through your site right now. That's an amazing setup.
What kinda of quarter mile numbers are your running with the lt1/T56 combo? I'm sure you're in the 13's.
How do you like the front 1le brakes?
Your car is basically the setup I'm going after....
Awesome!

Thanks for the kind words.
With my crappy driving. Best run I was able to put out was a 13.5 at 104. However I was not driving well and had rouble launching. I am sure the car is in the 12's with the proper driver.
The 1le Brakes are utterly amazing and I highly recommend them. That was one of the best modifications I did.
The subframes and the Brakes were probably the two best mods I did.

Really nice seats too. They look comfortable as hell.
My drive seat, although in great condition esthetically feels like i'm sitting on steel...lol.
Did they bolt right up without a problem with their brackets?
I'd hate to lose my power lumber and side support though..hmm..

Thanks.
I got the manual lumbar which is in the lower back area on these seats. The sides are very supportive and you dont need any additional support there. There is so much more offered there than in the Ultima seats.
They did bolt right in. Since I got the wide versions I had to slightly modify the seat rails with new holes to mount the seat to. It took a little effort but it came out excellent and I am quite pleased with the results.

How low can you go without scrubing the wheels, I have had trucks 2inches off the ground at the highest point(ahhh teenage years) so I know how to deal with the low car, but I don't want to scrub. I am thinking about some dropzone springs just because of the price I can get a set for, any experiance with them.
The price of the dropzones worries me. For less than 100us, I'm sure "you can't complain": but that's just it. If I'm going to do it, I'm going to do it right. Eibach is a name and spring I trust. It's one of the few.
The possibility of sagging/lossing handling with something like the dropzone's is unknown. Look at the Suspension Techniques line. Everyone around here was snatching them up a couple years ago cause they were so cheap. I know of more than a few people who are now removing them due to sag and horrid ride quality.

Here's a few of my car. Belltech 2" drop spindles in the front. The rear is lower now, but I don't have any pics. I also used a Spohn adjustable panhard rod to re-center the rear end. I have the relocation brackets as well, and let me tell you, they help a bunch in the launch dept.

That picture makes me want to give it some gas pop the clutch and go around in circles,
Nice car, do you have any trouble with the 2.5 inch drop with the wheel hitting the fender well. What size tires/wheels are you running.

When I first installed the spindles, I had a SERIOUS rub problem, every little dip and drop in the roap would cause the tire to hit the inner fender. The front springs were completely worn out and had no real resistance left. So I put in new Super Heavy Duty Napa springs, GR-2 struts and completely rebuilt the rest of the front suspension. Since the rebuild, I have only rubbed the tires once or twice, and that was on the interstate at 95. I'm running stock GTA wheels with 245/50 VR16's on all 4 corners.

Yea, sorry GTA-SPD forgot to pont out who I was asking, thanks for the info. I was worried about scrubing when I put the same wheel tire combo on my formula and do an 1-1.5 inch drop, but I gess I would be ok.
I know they are not snow cars. I live in GA we don't get alot of snow and when it does its wet, and freezes over quickly to ice, but I was about 40 miles away from home last winter and it started snowing and I didn't know it(inside no windows). That was not so fun to drive it home in 2 inches of snow. And unlike up north people down here still thinks 70 is a good speed when it is snowing, ABS isn't that good. I stayed slow and geared down to stop, didn't have any troubles getting her home but, man I didn't want to drive it in the snow, she's never been wrecked. I had to take different way home than normal, the highway was backed up due to a car pile.
now I know I want' scrub to bad if at all, the 15's I have scrub when I turn deep, but they are the wrong offset. Do you have any troubles turning deep.

I've got the Pro-kit as well and updated just about every possible piece to the suspension and brakes. By the way, the tire/rim size is 275 45 17 on a 4th gen offset TT2.
