Ok, winter work is about to begin. I'll have stock front torsion bars, new boge shocks and 19mm Weltmeister front bar.

With stock rear boges, what rear spring will work best for street with occasional fun runs and/or autocross?

100# Weltsmeister? or something else?

Should I spring ( (IMG:style_emoticons/default/chairfall.gif) ) for adjustable rear purches?

140's are a good balance with the 19mm bar and stock front torsion bars.. and Boge shocks. It will ride nice.

I like my 125s on adjustable perches, comfy, yet trackable (IMG:style_emoticons/default/driving.gif)

If he had ajustable shocks... I assumed he didnt want to spend any money on adjustable perches/springs for Boge shocks (not even sure if you can run threaded collars with Boge)

Im thinking about going back to stock front torsions and dropping my rear spring rate to 125-150. I have a Tarett bar. Which would be better for Autocross?

Stick with your current rear springs. The fronts need to be changed out so we actually have some room to adjust your front bar.

I'm open Thurs/Fri of next week. The torsion bars are free. You can install them. We will also cut down your rubber snubbers. We'll do it next door.

I have adjustable Koni's all round (set full soft), stock torsion bars, and 140s. Car seems very balanced for street driving.

So... 140s would be my vote on springs.

I just HATE the Weltmeister progressive springs. The car rolls first... then takes a set ??? HUH ???

Run a Eibach or H&R 125 or 150 spring.

(IMG:style_emoticons/default/agree.gif) I have the same setup on my car, works nice. I have a stock sway bar up front and I disconnected the rear bar. For Axing I just set the Koni's to full firm, 40psi in the Falkens, and hold on (IMG:style_emoticons/default/driving.gif) (IMG:style_emoticons/default/biggrin.gif)

See you at Sears Trekkor...

It is great we can AutoX 10 months out of the year with 2-3 events each month. All my "students" have done an awesome job this year.

Fronts firm and rears soft works great for me.
At Candlestick which had whoop-dee-do's and washboard surface, Brad set my shocks to soft all around and I was faster and more in control.

Here is what happens when you make a Koni change:

The effect: you are slightly increasing the front spring rate when you set them full hard and set the rear full soft.

Case in point: car is slinging the rear end around in tight slow speed corners... set front shocks more firm. This will keep the weight from transferring forward as quickly.

If you'll still be driving it on the street, 140 lb range should be good.

Why Boge? Consider getting some Bilsteins, they're made really well. From what I heard, a little better than Konis, but you don't get the adjustability - assuming that is important.

Depends on how competitive of a person you are, but adjustable spring perches or really nice if you ever want to fine tune or corner balance your chassis.

Where can I get a set of the threaded tubes & adjusting collars? I've been looking around on the internet and not finding much.

I am currently using Eibach springs and Bilstein shocks with snap ring grooves. The only adjustments are about 1" apart...
