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 ( ) 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

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.

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

Do you know what happens when you set the rears soft and front hard ?

Posted by: seanery Nov 4 2004, 10:13 PM

my guess would be that the car would rotate nicely.

Not really, it pushes.

Yeah Will go with a linear rate 150 rear spring. WIll go well with my rear trailing arms.

I just want to say, I love the way my car is handling and performing.

Brad, thanks for all the help!

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.

I went full soft on everyones cars at Candlestick. Too rough not too. Need to keep all four wheels on the ground.

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...

call Brad @ HPH....they should have them in stock....you'll need the 2.5" diameter springs...

Posted by: JOHNMAN Dec 1 2004, 05:10 PM

Awww MAN.....

You mean I have to actually pick up a phone and talk to someone. DAMNIT.

Thanks for your reply. Do you mean 2.5" Inside diameter or outside Diameter?

All I can remember about them is they are 350#/in and they are red. I'll need to measure one to see what the diameters are.

P.S.

I didn't mean to hijack the thread, and I missed the other one specifically about bilsteins until after I posted my bit.

Posted by: Mueller Dec 1 2004, 05:54 PM

350 pounds?!?!?!?

damn.....makes my teeth hurt just thinking about it

inside diameter of the springs, most common size for "race/sport" applications
