Default What spring rate do I have?

I have a 99 Camaro SS. Came with the SLP (sports suspension) pro-rate springs. What are the springs rated at? Specificaly the rear?

You know everything brake rotor related, but don't know your spring rates?

I know how to do a proper brake job yes. Spring rates arent posted anywhere in the stickies that I could find and its not and advertised spec with the car tha I could find.


If someone posted ridiulous information and I criticized them for it then so be it.

I've been wrong and taken abuse for being stupid before, its no big deal.
You learn something and move on.

If your unsure if you have the correct info then dont post it. I'll find the correct info one way or another.

If you want to be sensitive about your hole caking comment what the hell do you expect with such a statement.

Like I said show me a picture. Mine have not clogged once. The holes are countersunk, they dont catch and build up around the holes edges and because they are pass thru and the dust isnt induced until there is air moving, it doesnt collect. IF you've seen different I'd love to see it. Maybe with a home made drilled rotor ?

My Porsche brakes (4 piston Brembos on 13.5" drilled rotors) did cake with Hawk black and blue pads.

Wow, I've never had a problem. I've never heard anyone else say that except for you either. Were those the extra soft pad?? If so that could explain it, but thats a lot of dust. Was there a moisture issue as well at the time? My holes are as clean as a whistle and I brake hard.
I'll appologize for insinuating that you were making that info up.

Oh by the way the rates on my springs are k1 85.1 k2 191.5

If your SS came with the Bilstein Y2Y package, then it should be included with the SLP 70009 springs, which have a front rate of 300-450 lb/in and a rear rate of 115-185 lb/in. (of course you now list having Koni SA's, which I think is the right thing to do since SLP removed compression damping from the off-the-shelve Bilstein HD, and that's a no no when it comes to improving on the HD for handling purposes).

AFA having the SLP/Eibach 70009 springs, I have had personal experience of them performing worse than the stock springs, even with a 32/19 swaybar combo. Not only were they kind of floppy, but they also increased my lap times considerably.

If I had several combos to choose AFA spring rates are concerned, it's best to have either stock or some sort of linear rear spring that does not exceed 150 lb/in rate for the rear, when it comes to a good street/AX combo. I lists this generally and not specifically, since I too have desires to be competitive. AFA the front, there are several combo's I'd choose to refrain from listing for the same reasons as well.
