Had my oil changed at the local dealer (sorry Robin) and inquired as to the cost of lower the susp. with ROW springs etc.. I was informed that the previous owner had already accomplished this with Eibach springs (felt like a complete idiot)...I also noticed that there were Koni shocks and wondered whether these were standard issue on a 98 C2S...thanks

Btw...I've got a 2 star rating. Glad to see nobody on the list is judgemental! As a philosophical anarchist it's tough to sit by and watch technology erode your freedom.

The Koni shocks are not factory and are of sport valving. The Eibach and/or H&R springs work well with these shocks. Your car should be a fine handler and a bit more aggressive than the factory M030 setup.

Lonn,

The previous owner of my car also installed the Eibach pro-kit springs, although the rest of the suspension is original factory. The car looks great, and the handling seems pretty decent.

However, I suspect that the suspension could be better tuned with matching components. Like you, I'm considering the factory ROW M030 set-up.

Here are some parts prices I got for ROW M030 components a couple of months ago:

- front springs: 965.343.531.01 $350/set

- rear springs: 993.333.531.11 ? price

- front anti-roll bar ? part # / price

- rear anti-roll bar (21 instead of 19 mm) $175

- rear shocks (19 mm lower and different valving) $105 ea

I apologize for not having all the info, but the front shocks and front anti-roll bar are the same for ROW and US M030, as I understand it.

Maybe, I'll find that it doesn't really make a big difference over the less expensive Eibach springs method, but I'm hoping it will make the handling a bit more precise and composed.

Lonn, my '95 993 came with stock suspension. I bought the US M030 suspension from someone who was converting car to a track car, then bought the Euro M030 springs (front + rear) from Windward Performance for $499. Car with this combo feels great.

Your setup with Eibach springs and KONI shocks I feel should be great. Just might want to check the sway bars. M030 front bar is 22mm OD vs. 20 mm for stock. Rear M030 bar is 20mm OD vs. 17 mm for stock (18mm for wide-bodies and 19 mm for Turbos). This data from shop manual and parts manual (which I wish more people would buy!).

Thank you to all who responded...my Eibach\Koni set-up seems to preform really well (although I really have no basis of comparison)...had the original susp. been intact I would have gone with the ROW set-up but, to tell you the truth, it was quite nice to find out that somebody saved me the time and 2K...
