Hi
I am interested in upgrading my 99 corvette suspension..
I found many aftermarkets, I want the one that makes my vette stable, lower, easy to control on corners and gives her the race look while I am driving..
I want it as package..
any one here could recommend a package for me plz..

 

You can achieve your goals by lowering your car on the stock bolts to the maximum value recommended by the OEM, dialing in a more aggresive alignment and installing some tires with better grip. If you want to run wider tires & wheels, consider additional dampning (stiffer shocks) and increased diameter sway bars. Not much else is required unless you are going all out road racing.

There are many stock suspension C-5s running very good autocross times in both SCCA & NCCC. If you want to get the maximum handling potential out of your car, learn how to drive it first on a course, then consider changing your set-up to enhance your driving style.

 

Choice one, people will tell you to get coil overs and new sways, that will be $2500-3000

Or choice two, Get C6Z06 shocks and sways from GM Parts House for about $600

Or choice three, the Pfadt Johnny O'Connell shocks, sways and end links for about $900-100. I decided to get the JOC package as I have found it to be a great setup for the street and maybe some track time. I will be putting it on in the spring!

Do a search on the JOC setup and check out Bilstein and Koni as well.

 

How do you know this is a "great set-up" if it is not installed yet?

 

i've done a lot of research on this, and if you want to stay with a leaf spring setup, this is your best option for street handling performance:

-2004 c5z06 shocks
-c5z06 front and rear spring (if you have z51, you only need the rear)
-c6 z51 sway bars with metal end links and poly bushings will give you the best balance with stock z06 tire sizes. this is really going to be up to you though. use thicker/thinner bars in the front or rear to add oversteer or understeer, whichever you prefer.
-you can also switch to poly control arm bushings if you arent too worried about the ride quality
-get the car corner balanced

You can also go with some good coilovers instead, which add a few pros and cons:
-ability to adjust sprink rate and dampening
-ability to adjust these items for each corner
-much more expensive
-adjustment can be used to improve course times or just for better ride quality

i dont think the additional cost of coilovers is justifiable. even on road courses, plenty of vette drivers still use leaf spings with much success (However I might add that some use the T1 suspension setup). I would not suggest T1 suspension if you ever plan on driving the car on the street. it is way too stiff for bumpy public roads. if the setup is perfectly balanced, there wont be much difference between a leaf spring and coilover setup if any. I think the leaf spring setup is the best route to go for someone driving on the street who wants great handling without the cost of an arm and a leg for practically the same performance. Although if you are very concerned about ride quality, you may want to go with coilovers. However, if you adjust your coilovers to give you good ride quality, you are sacraficing performance. Personally, I don't care at all about the ride quality. in fact, the more you can feel the road the better. Some people dont like being beaten to death on their morning commute to work, but i cant get enough of it. To each his own.

 

I ended up with C5 Z bars instead but there isnt much difference anyways and it is much better than before.

 

I picked the JOC setup by the reviews and threads by others, I drive a little more aggressive than the average guy I think, so C6Z shocks and sways will be to soft for me and I am not spending the money on coil overs, so this setup seems to fall in the middle for me and I like the price for the package. I guess I will just have to see in the spring if this really is a great setup! I also have 325s out back and I am looking for cornering ability!

 

Interesting, have you even driven your car on the track at its limits or a C6Z on the track at its limit? A little different than driving on the street in a so called "more aggressive than average" manner.
A stock C-5 with sticky tires and a good track alignment is a very capable car, probably more capable than 95% of the drivers who own them.

 

If you're looking specifically for the best ride height control system available, it's probably time to step up to a full coilover system. Lowering the car on the factory bolts can give you some nice gains visually, but for the best in performance and ride height control set of coilovers designed specifically for the Corvette will allow you the best of both worlds. A C5 can be a very capable car in the right hands; the beauty of one of our Aggressor Corvette packages is that we not only provide the parts to help the car go faster on track, the cars generally become easier to drive.

If you're looking for a complete suspension package, we would suggest taking a look at our Aggressor 1 setup. It includes our Heavy Duty - Light Rate sway bars which are perfect for street use as well as track use with street compound tires, our FeatherLight Generation Single Adjustable coilovers for ride height control as well as adjustable damping, as well as our camber kit to eliminate the factory eccentric alignment bolts and move to a fixed shim system.

The Aggressor I package is still absolutely streetable, and will meet the original posters goals really well. Assuming the car is in Riyadh it would be much easier to purchase everything from one reputable company than try to piece together OEM parts from different sources for delivery in Saudi Arabia.

 

Thanks for all ppl who did the posts
I guess will go with complete package of PFADT
But now there are jhonney kit and others from PFADT..
I am still confused..

 

Here's whats going to happen. If you decide to go with the less expensive stuff just because its less expensive, you will more than likely regret it down the road. Then you will eventually replace all that stuff with a nice sway and coilover package from Pfadt, LG, exc. If you are ready to spend the money, go with the coilover set-up and be done.

 

That was to the point.. I agree with u

 

Unless your going to race it every weekend I would save some $$ and buy C6 ZO6 shocks & sways. I did and my C5 handles great. You can lower the car on stock bolts and w/the $$ you saved buy some new tires, G/L

 

I know this kind of hard to ask for. Im looking for a setup that will handle better on the street(i hit some curvy roads now and then) and also help me at the track when i drag race. It is a street car and will see some track time. i jusy dont want a drag setup because its not a drag car!
