I have an '84 corvette with the Z51 suspension. Can someone please help me out with the best way to lower the car? I have a ground effect kit and ZR-1 wheels with low profile tires. Lowering the car would look amazing. If someone can please help me out with how to go about doing this I would really appreciate it. Is there a kit of some sort available or can it be lowered as is? Thanks

 

The early Z51 cars were lower than stock already...

however, there are 2 ways to lower. Expensive and Cheap.

Expensive: Coil overs. $1,200.00 or so.

Cheap: <vendor name here> lowering kit. The kit includes 2 long bolts for the rear transverse spring and 2 lowering blocks for the front. The front kit is bit of a pain to install... $20.00 or so.

 

:iagree: the "longer bolts/front wedges" cost less than 50 bucks in parts but I think I paid over 400 bucks to have it installed and re aligned :eek: on my Black car - Lowered about 1 1/4"f / 1.5" rr.
The Ruby car I have has a C.O.I.L Suspension using idividually adj. "coilover" shocks and is about 1.5" or more lowered at each corner :flag Costs $1895 w/o FX3 adj susp and $2125 w/ FX3
Good luck :cheers:

 

Thanks very much for the help. I will definatly go the cheaper way and get the kit and do the work.

 

Thats probably the best bet. Thats what I did and I'm very happy. One of these days I'll go the Coilover route. All I need now is the $$ :lol:
:seeya :flag

 

The rear lowering bolts arent too hard but plan on a full day for the whole process. Ive done it myself so if you have any questions, feel free to email me.

Thanks everyone I really appreciate the help. We have a cold winter so the project will begin in spring. One last quick question. I bought a hypertech stage 2 chip, will I notice any difference in performance?

 

I'll be lowering mine this spring also :yesnod: already have the kit but with the bad weather I'll just let her :sleep: some more :lol:

 

I bought the lowering kit from mid america.......but after I saw what was involved in installing the kit I chickened out.....Just to much for maybe 1" of lowering....then realighning.....$$$$$
Forget About It......

Lowering the rear is very easy the front is a pita the rear is a 1 hour job
doing the rear only, makes the car level out.

Heres some C-4 lowering instructions for yea!!! It's so easy to do! Infact, the hardest thing to do is to cut the rubber off the spring.. that stuff on there is tuff!! Unbolt the outer tie rod & sway bar, on both sides, losen the spring retainers which is holding the leaf spring to the frame of the car. On either side that you what to start on first, get a block of wood ( 2 by 4 ) and a small floor jack will be fine, put the wood along with the jack under the spring closest to the a-arm, with out it being ON the a-arm it's self and slowly jack the spring up untill it's not resting on the lower a-arm ( about a 1/4 to an 1/2 inch off ) Disconect the ABS sensor thats located on the brake assembly, thats very important for you to do so!! ( if yours has one) remove the 2 bolts that are holding the shocks to the lower a-arm (they're located near the spring in the lower a-arm), unbolt the lower ball joint stud nut, you can use a two jaw puller or what I did was unscrew the nut untill it covered the end of the stud and with a hammer, tap on the top of the nut and not that hard or you'll ruin either the nut it's self or the stud or both. (try using a hard rubber mallet first) Before doing this, find something to put under the wheel hub.. another block of wood would be fine just to stabilize it and it should come free with no problem!! repeat this on the other side and let the presure off from the 2 by 4 and jack free and you should be able to slide the spring out from either side after you pull back at the wheel hub away little, the spring will slide out from the lower a-arm. It will not come out all the way if the car is not jacked up high enough and it does not have to!! you just need to be able to slide the spring far enough to be able to reach the rubber mounts. With a steak knife or I prefered a hack saw blade, saw off the rubber mounts and try not to cut into the spring it's self... take your time, don't rush!! (Helpful hint- While sawing the rubber piece, lift up on the piece that you've already sawed on, away from the spring while your sawing, that way it will not bind it's self between the rubber and spring. please remember this hint, it'll make work a heck of a lot easier for your self!!!). do this on both sides. this will give you the drop that your, I think looking for!!! The wheels will be, depending on what size rims you've got, if your running stock 17's will be about an 1 inch to an 1 1/4 from the fender wells, and NO!! THEY WILL NOT RUB!! You will have to of course hopefully with out saying, take the wheels off to do this job, and the ride is fine, just a little more stiff, and I do mean, A LITTLE!! This will make your car low!! I hope this helps!!! Aloha!!
