Anyone with MY 02 wheels.....did you change the springs size or use stock height?

If you lowered, by how much.

If lowered is the ride the same or much stiffer.

My car is almost done with the restoration, just fitted the My 02 wheels and looks a little funny with much more wheel well gap. I had new bilsteins installed with stock springs because I wanted the stock ride, not race car stiff.

I never measured the stock wheels, I have Cup Wheels..for get the size, but they looked like the same rolling diameter just by eyeball.

wow, that is really riding high. go with the M033s if you want a more compliant ride w/ lower stance.

Rockit

Can you give me more details....M033's are what shock or spring?

+1 ^^^, you did not mention which Bilsteins you installed. Most 993 owners go HD, but there are Sport versions also. Sport springs are M030.

Rockit

Ok are the M030 springs shorter?

I'll find out what Bilsteins I have, I'm not sure, I wanted stock struts and springs.

This explains it pretty well

"What's the difference between the M033 and the M030 springs?
The M030 is a sport suspension. The M030 springs will make the ride lower and sportier while the M033 springs will lower the car the same amount but it will remain comfortable just like the stock springs".

It's not your MY 02's which are the standard diameter (and beautiful, light weight wheels). My guess is that you either have the wrong springs, or they're not installed correctly. Dayem that's sitting high.

Thanks....I just checked my records I have the HD Brillstein's but B6

I would need the B8 shock with M030 Springs

Thanks so much for the fast response and info!!!!!

You can use the B6 with the ROW M030 spring. Thats the setup I have.
The B6 has extra thread on the collar for height adjustment. The B8 has less thread on the collar with a shorter piston stroke.
Either B8 or B6 will work with ROW M030 springs.

Looking at the picture of your car. Are you missing the interior or other heavy items? The car might come down a bit when some heavy items are back in.
Maybe you should wait to see how it all settles before buying new springs.

Rockit

Thanks....are you sure?

I looed again at the Cornwell site and did does say nothing about the B8 being better as far as stroke.....

Thanks 911F1!!!!!! You just save me thousands...!!!!

Oh. the seats and door panels only are out.

The B8 does have a 20mm shorter stroke
Quote from page:

"The Bilstein B8 shocks have the same damping as the Bilstein B6 but the stroke of the pistons is 20mm shorter. Due to the shorter rebound, it makes the Bilstein B8 an excellent match for the use with RoW M030 and M033 spring as it eliminates the "floating spring" issue which you will have when you combine B6 and M033 springs."


Just make sure your bottom spring perch on the B6 shock is threaded up tight against the spring when installed, so you don't get the spring float mentioned in Carnewals quote. The B8 with the shorter stroke solves this with the shorter stroke. Thats why they say the B8 is a better match. But B6 or B8 will work with ROW M030 springs.

For it were me, id keep the shocks you have but switch to M033 springs. The result should give it the lower ride height of the European models without the "race car stiff" ride you wish to avoid.

I see you have the answers, but the last thing you would want is the stock Monroes n springs. And yes, the M030 springs do lower your ride height, but I would look at the adjustability you have in your Bilsteins before thinking about buying springs.
A KT alignment and corner balance are in order as well.

The whole b8 shock is shorter than a b6, it is usually used when you want the car as low as possible

close to this low


there are also Us springs and RoW springs

unless you want the car very low i'd use b6 and RoW M030 or for a softer ride RoW M033

lastly your car needs a complete suspension setup ,as it is now it is too high and I can see that the rear kt is set to give a very fast twitchy acting rear, get a corner balance and proper alignment including kt after the suspension work is done.

Here is my old 993 with Koni's and M033 springs.
