Default I Need suspension knowledge..

Is anybody out there willing to educate me on what im sad to say i already bought? Well not sad as i researched prices of the parts and got extremely good deals on everything..
So here's the deal, i bought Qa1 Drag shocks from a member on the C6 side. Front double adjustable backs are single. I also picked up a Pfadt rear drag bar was told its a "Light weight".
Its not a track car and just my little hot rod street machine. So my questions would be what setting do i want these shocks at for street driving and what for track vs Drag strip? Is this a good combo? Will this still perform well in corners even though its all "Drag" related?

in case it helps I am running a TPE wide body with factory take off 2012 GS wheels and tires.

And if i can ask one thing out of all this PLEASE NO TROLLS.. I dont care if you feel i should use the search button because I didnt get what i was after when i did..


Thanks Jon

The short answer is no, it really won't. Drag shocks, and in particular the rears with only one adjustment won't handle very well, but they will hook you right up on the strip. The problem is that the compression damping isn't what you want for good cornering and you can't change that.

For the street, the fronts could perhaps be ok, but you are giving up a lot of performance relative to a properly valved shock like the Bilstein sports or the 2004 Z06 shocks.

If the rear sway bar has some adjustment and you can set it close to stock then the car won't oversteer and drive like an old VW, but changing the rear bar stiffness and not matching that change with an equal bar stiffness change in the front will result in a car that pushes like a pig or oversteers big time. Neither one is very much fun, so you need to match it to your front bar. If there is a setting that will let you get to where the stock bar was in terms of stiffness, set it there and leave it.

If you are going to run the car at the strip you have some good stuff, but if it's a street car you are going the wrong way. With that stuff on it, it isn't going to handle very well. If you are just driving it in every day traffic you might not notice it. If you are going out corner carving once and a while it's not going to be very pleasant

I'd get it touch with Pfadt and the can recommend the correct setting or a matching front bar so that you don't screw up the handling too much.

As far as the shocks go, you might get the fronts to work with the range of adjustment that you have, but the rears are pretty much hopeless as far as handling goes.

The problem with drag specific setup is that they're great for going in a straight line, but aren't great at doing much else. You can typically make a Street or road race suspension work Ok at the drag strip, but packages really optimized for drag strip usually don't work particularly well when driven hard while cornering.

Know that you're going to give up a good amount of handling ability if you're running a drag shock on the street. Some folks don't mind... if your into street racing or just cruising around town it will probably work pretty well for you. Although if you take the car for a spirited run in the canyon or to a local Autox or track day you're definitely going to be able to tell the difference in handling. Also be careful if you're going to drive the car hard on the street with our Drag Bar... It's an extremely stiff rear bar from our Heavy Rate sway bar kit, so the car will likely be prone to oversteer depending on how the front shocks are setup.

If you would like some suggestions on how to maintain a great balance of ride quality and handling we can definitely help you get there. The parts that you've purchased are worth installing on the car, so long as you understand there will absolutely be handling trade offs, and the car will probably never handle as well as it could with a more balanced package installed.

This is the best answer i have ever got from the forum.. i've been throwing up all day but if i get feeling better tomorrow i will give you a call..
I do want some fun in a strait line for a year or so but i know in the back of my head i want the newest Pfadt sway bars and coil over shocks.. i just need to get this car finished and i already have a buddy that i think wants to buy this setup from me so i will have a big chunk to throw right at it..

Thank you both for your replies i really appreciate it..

Jon

I think the name "drag specific" says it all.

You can "soften up" an aftermarket bar by replacing the poly bushings with RUBBER and vice versa--you can stiffen a stock bar by replecing the rubber with Poly--Energy Suspensions says the difference is 30% !!!!!

They should get you working on this whole Cancer thing. I guess they're having a hard time with that too.


And I just did a little research...
your ONLY thread is about TOYS...
please don't post up when you probably couldn't answer the question to begin with...
