what do you guys do suspension wise?

motor is a forged 408 making 500 rwhp and i'm running a 200 shot

trans is a rpm level 6

converter is a yank 3400

rpm diff stage III with quaife.

drag pack with 26 x 11.5 et streets

what do we do for suspension on the c5's??

 

In general, disconnect or better off remove front sway bar. I have seen gains of a tenth of a second.

 

No way..
Disconnect it, yes...
Will never see 1/10 from it...

 

adjustable shocks will help you tune to the track
some say lowering will help you 60' but mine is stock height and have gone 1.37

Search though this section for pfadt and ECS they have come out with some new products recently.

 

I am not an expert at drag suspension, but I am running the Pfadt coil overs / drag setup that includes the newer hypercoils up front, all mounted on the updated split spherical bearing mounts. This is along with pfadt adjustable aluminum sway bars and a Pfadt Transaxle Load Distribution Brace.

I've blown both rear coil-overs with this setup and was asked to take my car off the track at an event for leaking oil (from a blown shock). And, although the shocks were replaced at no charge, the labor was not. Therefore, until Pfadt works out what's happening with the rears, I am not sure I would recommend their coil overs on the rear.

I believe that Pfadt is a good company that designs good parts and am not complaining - I'm still using them (with dampening now set to max). I'm sure they will work to correct whatever may have caused this. But, you may want to contact them prior to running coil overs to chat about this.

I also know that ECS has been testing the Pfadt setup and may be able to offer more insight / advice.

This is just my opinion... But, feel free to blast away at me

My C5: Forged 346 with Paxton Novi 2000, RPM tranny, Getrag 3.42 Diff. (going up to a 3.73), Yank 3200 (going to a Yank Pro 3800), 26x11.5-16 rear tires, etc... weighing in at 3600 lbs with driver, producing ~770 RWHP & 687 RWTQ

 

Thats interesting you had issues with the Pfadt coilovers. I just bought a set of Penske coilovers and was this close to buying the Pfadts as they are local to me. Looks like I made the right choice,keep us informed of how yours turn out please. As a side note,did you feel the coilovers(when working properly) helped your 60s ?

 

Not sure about the 60's as I never ran the car on another suspension. But, I've never had a problem hooking up and have no tire hop, etc.

As it sits now, the car is usually in the 1.55 range for 60'

I think the change in converter and gears will do more for my 60's than the rear shocks... But, only time will tell

 

Keep in mind as we enter the era of throttle managment, 60's are influenced by throttle settings. Dave was your 1.55 100%?

 

Edgar, that's true... Sorry that I forgot to mention that.

No... I've never run her at 100% -- Typically, I am running between 60% and 80%, depending on the weather.

 

Yeah that much power you gotta be quicker in the 60'

I got your back brother

 

But, a centri blower isn't fully pumping off the line... Consequently, swapping the converter for a higher stall and changing the gears (both just a little bit)... I'm interested in getting that 60' up while getting those traps down

But, we digress... This thread is about the suspension. So, I shall shaddup now... Even though I do like powahhhh

 

how much does a coilover setup run? man.. i'm so stuck on.. "what to do next".. lol first 500 rwhp was going to be enough.. never even ran it at the track yet.. and i wanna install my nitrous kit. .. but first i need fueling..lol and then suspension.. i dont know how you guys do it man..

i give myself a headache thinking about it all.

 

what WILL it do for me?

 

It can get quite insane But, I suggest that you try a few runs before any more mods. There is a good / recent thread on this that you can read at:

http://forums.corvetteforum.com/drag...ag-racing.html

Some of the seasoned drivers provide some good insights in that thread. First find out how much you like racing and then after getting some seat time, figure out what mods (if any) you want to do first, instead of going right to the suspension. Otherwise, you may end up replacing mods, which will cost you more in the long run.

With the power adders you mentioned, you may need a roll bar / cage well before a suspension ;-)

Good Luck!
