hey all i know this is a pretty popular thread but i couldnt find anything on it.

my z06 is lowered fully on stock bolts but its not enough for me!

i bought new bolts for the front..just rather know exactly what to do when im getting into it rather than staring at the suspension for a half hour..is there any threads someone can point out on a complete install of new front bolts.

also

i wanna get new bolts for my rear.. ive read a thread on here while back that u can get the bolts at a local hardware store rather than spending 50-60 bucks from a vendor.. does anyone have the specs of the nut bolt package i would need..

thank you!!

 

you can also cut the bushings to go lower.

 

true that..but id rather just install the new bolts =)

whats the difference in cuttin the bushings rather than installing new bolts..wouldnt i have to take out the stock bolts to cut the bushing anyway..

 

I just installed lowering bolts in the front of my Z last weekend.

Here is the procedure I followed. Not all of the pictures worked, but the text is enough.

My lower "A" arm bolt wouldn't budge after beating on it with a rubber mallet for 30 mins... so I just took off the Upper "A" arm bolt, and lowered the A-Arm from the top. Same result, not much more work. Keep that in mind if you run into the same issue.

Enjoy.

 

No, I cut mine without taking anything apart. takes about 1/2 hour. + Elbow grease.

 

It would probably take you a little longer the first time if you've never done it before and are a normal weekend fixerupper. After you've done it once, 30 mins dependent on how fast you can get your car in the air. IMO of course.

I'll post some pictures of mine as soon as I get a nice day to wash it up. It's pretty filthy right now. I still wish it were a tad lower. Only thing i could do is totally remove the bolts.

 

 

thanks pchild for the info and the instructions

any specs on the bolt, nut setup for the rear??

 

If you're pulling the front bolts out and putting in new bolts you'll see how it works.

The closer the bushing (over sized washer covered in a hard plastic/rubber) is to the leaf spring, the closer the A-arm is to the spring, thus lowering the car. The front bolts are reverse threaded, so they tighten and loosen the opposite of what you're used to.

I personally screwed my new bolts in as far as they would go. I'm lowered max on replacement bolts. I have pictures of the new bolts vs the old stock bolts with bushings, maybe tomorrow i'll post pictures so you can see the difference.

It lowered it maybe 1/2 and inch lower than stock bolts.

So it's up to you how low you want to go. The roads where I live are fairly decent. I don't have to worry much about bottoming out. I know the roads well, and know what spots I have to avoid. I have how ever hit construction in my previous C5 when I had it lowered, and hit hard on some roads I wasn't fimiliar with. So if you're asking for my opinion on how low to lower it, do what you're comfortable with. Lower looks better, higher is safer for the car =]

I think the A-Arm bolts were torqued to 55 foot pounds, and 35 foot pounds on the shock, and sway bar.

I may not be 100% correct on that, and TBH I don't own a torque wrench, i have to bum a friends when I need it. =P

 

for the rear bolt you want a 9/16 grade 8.problem is,you will want it 7" long and most hardware stores only carry up to 6".i called 5 different fastener stores and only 1 had them in town.

the thread pitch doesn't matter,just get locking nuts to fit the bolt thread.you will also want to pick up 4 washers.somewhere around 1 1/2" diameter.

 

Difference between stock bolts and the lowering bolts I got from Mike Yeager @ Eastcoast Performance.

Stock is the one with the ugly worn out bushing.

 

Thats the path I took.

 

i bought the lowering bolt kit from Zip. Worked great, the stock bolts didnt go low enough for me either.

 

thanks again pchild and thanks jonnyC i found the bolt specs from another thread and will be looking for them soon..cant wait for some clear weather to pull out the vettes and get mine on the lift for the install..

i am worried tho cuz i live in suburbs of chicago and the roads out here and fairly decent cept for railroads and ur good ole buddy pot holes.. but i cant avoid the looks of a lower than low c5 z06 haha.. it may take me a couple minutes to get across railroads but im willing to handle all the bitching and yelling from traffic for the Looks
