2.5" or 2.625" 8"/10" coil's will be used...
currently have 19mm tbars, and 180 progressives,
upping to 22m torsion bars, and adjustable coilovers in the rear...
what spring rate would make a good balance.... that i could fin tune with my sway bar
-AA
220? 250?
Thats what IM going with... and I have a big v8 in the back....
but.. then again, im running the stock front sway bar.
Bigger motor...

What sway bar? Factor it all in.
The Tarret on full soft doesnt like anything over a 22 front bar unless you go 225plus in the rear. The car ends up riding like shit.

I have 22's with 225's in back, with the rear swaybar hooked up (full soft). Without a rear bar I think you'd want 250+ as pointed out above.

Tarret Sway (can set anywhere) Stock Rear Bar current setup blows. kinda pushes, gotta play with more sway bar etc... 200's? |
Here is what I have done on Trekkors car:
Stock T-bars and a large bar. A sway bar set on full soft does me NO good. The only other thing you can do is disconnect it completely and run the car. I want adjustability. Just recently we ordered 5 way adjustable front and rear bars for the Boxster because nobody offered anything more than a 3 way for the rear.
If you have stock t-bars now and a bar set on full soft.. and you cant get oversteer.. we need to chat.

Also, where do you guys get your rear coils? (2.5 or 2.625?)
Jim Johnson (SCCA 914 cuy) said to try some dirttrack places....
so im thinkin tarett on soft, 22mm tbars, stock rear sway, and 200 lb springs.
22mm Torsion, 175# springs working REAL well for me.
Torsion Bars & Springs should be just big enough to keep the car from "bottoming" out. Understeer/Oversteer set with sway bars.

Brad- i missed your post (snuck it in as i posted)
i have 8's and 225's on the the rear, with 7's and 205's up front. i CAN get oversteer, but then the car leans a bunch...
I hate the weight transfer i get with the stock torsion bars (911), i go hard accel to brake, and it nose dives a ton... but the rear doesnt squat much under super hard throttle.....
Ken - springs are about 50 ish a piece, maybe ill start at 175's and play around from there....
What I have found with *some* of the dirt track springs: Inconsistant spring rates on the tester. Pay for an Eibach or or H&R. The club is setup with the West coast distributor for both.

I didnt realize you where running 7's and 8's now. As far as nose dive under braking: Dont brake as hard. I'm reading more and more data on pro-drivers and I'm seeing them brake early and semi softly and get back on the gas. It baffled me the first time I read data on Randy Pobst. Just from his data I could tell when he was passing somebody under braking and when he was running a clean hot lap. His braking points and "on gas" time totally changed.
I'll have to think about the 7's and 8's.
