Hello there

Won't be installing my new Pedder springs until the Spring

Anything i have to do on the car while installing? Bump stops etc...?

Front wheel alignment after ?

Thanks

 

Anyone?

 

Just change the springs. Leave the bump stops alone, and the alignment should be fine. But it wouldnt hurt to get it checked after your done.

 

sell them too me and i will install em now.

 

I would def do an alignment after any sort of suspension mods.

 

Rack spacers are recommended to minimize bump steer.

Bump stops don't need to be cut, but you can get away with cutting just the "dome" without any negative effects.

Some people have had to trim the little lip on the top of the rear spring seats, but your mileage may vary as not all pedders are coiled the same at their ends.

Definitely get an alignment.

 

petroleum jelly for install

 

You'll need an alignment after. Get rack spacers, the thin ones, unless you have rotated engine mounts.

I'd advise loosening the front big strut nut while the car is fully loaded. It will be easier, since it won't want to turn as much. For the rear springs, I had to trim the bumpstops and break out a mini torch to get them to go into the poorly shaped spring ends. You'll see when you try to put them in. Some people managed to just lube and put them in, but mine were no where close. Make sure you put them right side up.

 

this.. try the lube method first. ive installed a few sets and lubes worked everytime but like he has said. others have been more of a pia.

 

Oh, one more thing. Make absolutely sure that the front spring mount and top hat are turned the right direction! Before you compress and disassemble the stock setup, notice the paint marks. You need to put it back together with the paint marks lined up. Or just turn the tab (you'll see it) inwards, towards the engine. I face it directly opposite of the knuckle mount.

 

Note to Wangspeed, good guy with good advice; the tab of top plate has to line up with end of spring coil at top. Pedders are cut differently from GM often, so the tab position will not always face in as a result....

 

Hmm, when it's not so frigid, I'll have to take a peek to see how far off from the end of the spring I am.

 

Your running Pedders Wangspeed?

 

Yeah. Overall I give them a 4 out of 5. For street and light track use, they're good. I ding them the 5th star because they don't publish any spring rates, and the fronts, as I've found, are a little too soft for more serious track work. Of course, to maintain balance, if the fronts got increased, so would the rear. I get some coil bind up front, as evidenced by the fact that I've worn off the powder coat where they bind. Also, for springs this expensive, they could at least wind the ends on the rear springs in a circle, not a D pattern. That's pretty poor given how much we're paying for them.

I think the Pedders + OTTP/PRS rear sway bar are more than the rear shocks gracefully handle. I didn't think much of it til I moved to Konis. There's quite a difference, and that's with the Konis adjusted conservatively. If I ever get my shock dyno plots back, I'll share them.

Do I think they're good? Sure, but they're overpriced for what they are (or aren't).

 

Good info, thanks everyone. Pedders sitting in the garage waiting for install. I know if I do it now it'll snow 12 inches.
