nice pics & everything, but i didn't remove the wheels or disconnect the a-arms.

i drove up on ramps, then disconnected the sway bar where it attaches to the frame, then pulled out the two bolts on the bottom end of each shock. then jack up directly on the leaf spring one side at a time...get the leaf high enough to put a prybar between the lower a-arm and lift up on the leaf that way. Then pull out the front bolts/bushings no prob.

a lot easier and faster then removing all that other stuff, but it does require some upper torso strength.

for the rear end, just jack up on the leaf a little, pull the bolt out and switch it. don't leave it without a bolt for very long with a hydraulic jack-they bleed down.

anyway, just a different way of doing things. good write up! your ride looks sweet btw

Ya,thats cool,iv'e done it like that too,the long way is safer,i really don't like to post dangerous procedures.I also did the rear like you mentioned.And once the new bolts were in,i did all the adjustments without jacking the car,just reach under,half turn or whatever.I must have done that 50 times (over a weeks time)in the rear to get it perfect,gets to the point were you only turn one side a 1/4 turn at a time.

The other reason i did it the long way,(now my secret is out),i had to remove the spring,because along with removing the front adjustment bolts,i trimmed half of the rubber from the inner spring brackets,(rectangles),i took half the rubber from the top side of the spring,and glued it on the bottom side rubber that was already there,then put the brackets back on and tightened.
I saved the rubber i cut off (now under spring),because i didn't want to trim the aluminum brackets to make-up then space i cut out.I could go lower,i actually was lower,but i fucked up my right side rocker panel real bad a couple years ago.Didn't have the frame savers.

I'm curious how low you guys went.Heres my ride height...
Front... - from floor to top center of fender lip 25 1/4 ".......(used to be 25 even).
Rear... - 26 1/4"...(used to be 26" even)

Lower rear front fender,were lower fender seam meets the door seam,and wraps under the car...
go to the lower rear of the front fender,were the seam meets the lower door seam,but under the car/bottom,i took a measurment from the flat/underneith section of the fender (next to the little fender bolt).....from the floor to the bottom i just described,is 2 3/4 "....

Thats with stock zo6 wheels sizes 17/18.

what size are the stock z06 wheels? ie 245-40-17...that'll change the height of the fender measurements too, right?

you've got an inch on me todd! but i wouldn't want to go any lower with the streets around here :cry:

Front: from floor to top center of fender lip 26-5/16"
Rear: from floor to top center of fender lip 26-9/16"

i measured behind that little bolt, and came up with 3-3/4". and fyi, the distance from the jacking pad to the floor is the same on all my 4 corners.

that is on stock 245-45-17 / 275-40-18

i bet the rear measurements fluctuates with different gas levels a bit too.



just a thought, as this is a pretty popular topic in this forum: maybe we could get a sticky at the top of the c5 section with instructions, and the heights of everyone who has lowered so we can compare?

You guys are pretty low too.

Z06 tires are wider,and a 1/2" shorter (overall diameter).So i had to go lower to close the added gap after changing from the run flats.

My long term goal is to put 19 front 20 rear.....without raising the car.Not a problem.Just need to reseach the tire diameters.This might suprise some.These are all rear tires.
Overall diameter + height of tire from top to bottom.

Eagle F1-GS (C5 RUN FLAT)...275/40/18..overall dia..27.7"

Eagle supercar tire (2003 zo6..which i have)..295/35/18..overall dia..26.1"

Michelin pilot sport..(note the 20" tire,is actually shorter than the 18 inch tire)...295/35/18..overall dia...26.2"......285/25/[b]20[/]b..overall dia....25.6"....they also have a 30 series 20" tire that is 27" tall...got these specs off the tire rack site.You can see that when you go big tire,better know what dia your getting..

I'll see about the sticky thread...
I'm going to guess ALLKAR is the lowest..(body to ground/as well as wheel gap.....

Cool,what rim/tire package are you going to use.If i dropped another inch (which i can without coil overs),my tires would be rubbing the the fender,the top of the tire not the sides.The tire i have now is 26.1" tall,that leaves me almost a finger to stick in the gap.Another inch and the tire would be hella tucked in the well and rub the top inner fender.A mini-tub would be cool.I really can't go lower as our roads are filled with pot holes,some are deep enough so the body will hit as the tire goes in the pothole,and driveways on an island are steap and short.
I look like a drunk driver as i'm constantly dodging potholes and boulders that roll off the mountains into the highway near my house,my best thing to run over yet,was a alternator bracket from a truck.That made some evil sounds passing under the car.I couldn't change lanes,so just angled the car so as i hit the damn thing it would not gouge open my oil pan..

19&20 Motorsports.I went from CCW 18" Classic package and my 19/20 combo is shorter diameter then the 18's.Allkar and Vettret both have 19/220 combo too.They just have I-forged and I have Motorsports.

Cool,your ready to go then.My fav rims are iForged aeros.
I like the aftermarket rocker panels ALLKAR has,it enhances the slammed look.
I'll be looking for your pics when your done..

Has anyone thought about doing a reverse spring mount? Mounting the spring under the front A-arm
like the rear. You would have to drill a hole through
the A-arm for the adjusting bolt. I would think that the spring would be tightend enough to ride close enough to the A-arm, so ground clearance should not be a problem.
24 to 24.5" ground to fender should be no problem
with this.
I'm not sure about the clearances (spring contacting the A-arm), but as soon as the weather warms I'm going to give it a try. Dropping over $2000 for coilovers to get that extra 1" sucks.

I had looked at that briefly.A while ago,it seemed that if the car would bounce,if the spring was on the bottom of the a-arm,but really can't tell.It's one of those things that would just need to be tested.
iI would like to see your results if you try it though.

I had thought about grinding the a-arm pad down,might be to weak.
I thought about making extension brackets,that would bolt to the alignment bolts (cam bolts i think),the a-arm could then drop down some,to much fabrication for something that might not work anyway.Then alignment would be a pain.
I thought about taking my stock a-arms to a machine shop,and having some tubular steel a-arms made with a lower angle going to the subframe.
Or even trying other a-arms from other cars.

I can get under 25" with my FE-3 sport spring by removing the rubber at the top of the spring from the inner spring brackets.I remove a 1/2" already,that got the car down to 25" even,but i trashed a rocker panel,raised it up a 1/4",and never got back under there to remove all the rubber from the top of spring.

I really want to try something with the stock spring, because I would like to try these for the front. They must be used with springs not alone.

I've seen a couple of good write ups on these. They have come a long way with air springs.

I am a huge air bag fan,not sure how they are for drag racing though....Always wondered if someone would make a vette kit.
Who's selling those air shocks in your post?

There from Air Ride.

You can use them on the front. They don't make a Rear for the C5.
