Let's talk Coil Over Spring Preload
Guys,
Working on my track setup a little more. Now want to play with Coil Spring Preload on the Pedders Xa's. Right now sitting at 5mm preload on all four corners. Talking to some guys that road race cars say to run 8mm in the front and 3mm or less in the rear. This will aid in nose dive under hard braking and provide good weight transfer for the drive off the corner. Anyone have any information that they would like to share. I know that this is a lot driver preferance. What may be the optimum for our Camaro's? Later Ralph

I would ask Pete for his opinion, and then do whatever Pete says. I'm not trying to say just blindly follow what Pete says because that's not what I'm getting at, Pete is The most knowledge person when it comes to the 5th gen camaro's suspension.

I think I would use preload and ride height to set your corner weights. find a good shop that can corner weight your car properly and align it.

Camaro has been corner weighted and is pretty nuetral. But had about 5mm negative rake in the car at that time. I just changed the ride hieght a little to help with rear axle heat. So now I am 5mm positive rake. So this will add a little more weight on the nose. Adjusting spring weight in a static position say 45% front and 55% rear weight. In dynamic position the weight transfer under hard braking may be 55%F & 45%R. Thus exiting the corner the transfer may be 40%F & 60%R for the rear to hook up. Also running 140 mph down the straight and the spoiler being able to plant the rear for stability. Is a softer spring setup in the rear the way to go and heavier spring in the front for corner entry. Just some thoughts! Love going to the track and adjusting and figuring what works best for me.....and helps turn faster lap times

Hmmm last Xa instructions I received said 3 mm preload up front and 10mm in the rear. I do play with it and have mine at 5 all around.
Last advice I got from Pete (driving my car) was to put the front sway to full soft and full hard on the rear bar.

If you setup like the other guys how are you going to beat them With Pedders Xa or Supercar coilovers there is only one way to set the pre-load. My way Front coil preload 2/3mm Rear coil preload 10mm I'll be happy to discuss your setup details here on the forum or privately if you are looking for an extra edge Here is the information I need from you.
With this basic information we can into a detailed setup discussion. |
