Decent track suspension..?

The SM Evo I mentioned earlier had 650/550 springs (I think) and the *** end hopped its way through sweepers until you put the power down. Don't know what NF that translates to though.
2.2 front, 2.5 rear would be 450/675.

EDIT: as for hopping though sweepers, my car would do that when I had JICs. I am convinced it was the excess bump damping. I set it to be just right in slaloms then it would skate right through a long, steady state turn.

You know....i typed that, then i remembered that Dave Mac had rates right around there with his RE-01R's. And we helped set up his car. Oops!
- Andrew....should have said Falken FK451's or whatever their crappy all season tire is. I have seen that and that's what I meant!

Hmmm... I know the guy who won the Pro this year. I don't think he's running quite that high. He won't tell me of course (well, I haven't really asked), but just from watching his car all year long, I don't think his rates are that high.
It actually does make sense to control roll with the springs. I think the key is getting the geometry right. I'm building my car for BSP (or maybe ASP by the time I get there), so my only option is camber plates to correct the roll center. I'd like to see what zzyzx comes up with for their design. I hope its something like the DMS plates, which are freakin awesome.

Looking forward to seeing how you like the zzyzx stuff by the way. Definitely post your impressions when you get them.

I have also traded some email with Steve but became disinterested after thinking that he was going to have the same problems with rust and corrosion that the DMS 40s did. Now I find out that they are cadmium plating everything and powdercoating what they don't plate.
I'm about this far away from placing an order.

What is there to get all confused over? Its really not all that complicated. He asked a question. I quoted the particular question i was going to respond to. Rather loosely speaking, he wanted to get our perspective on a few issues. He mentioned John Mueller in a few posts, and that he was probably going to have him set his car up. The way he spoke of him i suspected that he has been in contact with him. If not, he knew enough of him to mention what he did about him. Since John is the individual who has set my car up, i felt i could be of service by providing some info. And so i did. It didnt seem like he was asking questions about equations and constants, so i kept it rather simple. If he wants more details from me he is welcome to pursue it, and i will do my best to help answer his questions.

You should see what they do to get camber out of a stock 911. Suffice it to say, I was able to do 28's or 29's at Willow in basically a stock 3.2L with sway bars, AND NEVER ROLLED THE TIRES. I ran that car in a "Production" class, and prolly will never run a stock-ish class again with a car I give a crap about. It's funny (if it's not your car), but they beat the living poopie out of the thing to get settings that you'd normally never see in a stock car.

BTW, I would read up on suspension tuning a little bit. Its really not that difficult. You can have your car tuned by the professionals, but you may need to tweak it for different surfaces. You need to know how to fix it when its behaving badly. Dennis Grant's web site is a good starting point, but there is a ton of information out there.
For instance, you'll probably want to upgrade to an adjustable rear sway bar, and possibly upgrade the front as well. Any of the various bump steer correction kits is a must if you're lowering the car and tracking it. The front roll center correction kit from Whiteline I hear is pretty good too. The same effect can be gotten with camber plates, but then you need two camber adjustments, one at the plate to correct the roll center, and one at the spindle mount to correct the camber.
