weltmeister springs - which do you suggest., how much difference is there between #100 & #140's? Options

[DRPHIL914]

I have a 75 2.0, with 8spoke empi 15" 4 lug, and 195/55 performance tires. Currently have bilistein sport shocks, adjustable with newer #100 springs. When set higher to give better clearance its pretty bouncy, so I moved them down 3 notches to take tension off springs but before I rolled the fender lips they would have almost zero clearance on outside.

Would going to #140s help. I know there is an inch diff in height so if I put the shock setting higher- more pressure on the spring I will get a little higher ride, but will it be too stiff for daily driving and the occasional d.e. on the road course- robeling road? It should bounce less but .

Anyone used this combination? I've not had the #140s but have a chance to buy some.
Need some I.put to make a decision on this.

Thanks

Phil

I also have stock sway bar with new bushings

Hey, I thought that Bilstein shocks are not adjustable in dampening/rebound?

Do you mean that you adjusted the spring perch? Raising and lowering the spring perch will have no impact on ride.

I did the googles on the intranets (IMG:style_emoticons/default/laugh.gif) and can't find any Bilstein Sport shocks that are adjustable... Please clarify, as a complete answer to your question relies on this attribute.

SO, either way, here is my opinion.
If you have Bilstein sports on the back and no anti-roll bar, use the 140# springs (as they are a better match for the Sport shocks) and use the Koni sport snubbers.

If you have an anti roll bar in the back, go with the 140# springs, but stick to the stock snubbers.

The Koni sport snubbers will allow the rear shocks to compress an amount before significantly increasing the combined spring rate. This would be best for a car with no anti-roll bar as the anti-roll bar increases the combined spring rate in a corner as well.

Now, what are you running in the front end? I would think you need to match your suspension. You could get by with 19mm torsion springs if you have Bilstein sprot struts upfront. As the front of the car is lighter, the front of the car will have a bigger impact on the actual ride of the car.

I hope this helps.

I have sway bar with new bushings,
the shocks are adjustable in the location of the retention ring location for the spring, so you have a higher ride with morepressure sooner on the spring, or if it is lowered, then more demand on the shock,less on the spring and lower ride.

I have not gotten to the front. The back was bad old koni and weak springs.
The front is the next project. It feels good, but will atleast need the sway bar as zach said.

What are snubbers?

I don't think that there is any different in shock demand based on spring height perch. The car will settle to the same spring height no matter the perch height. The "more pressure" you speak of is only applicable to letting the car off the jack.

Does this make sense?

A snubber is the rubber device that keeps the shock from completely collapsing, protecting the shock mechanism and in the case of the Koni snubbers adding spring rate as the snubber intersects the shock body. (IMG:style_emoticons/default/driving.gif)
