For those of you interested in jack rabbit speed 0-120 with your manual tranny, take a look at replacing the rear end gears and changing the ratio from the current 3.27 to 3.46 or 3.69... http://www.bergwerks.com/differential.jsp http://www.bergwerks.com/different_appli.jsp

I am in the process at BergWerks here in LA because I race the car quite often at many CA road courses and have found the gearing is too low for all of the tracks I race on. And also too low for average freeway driving 65-70 mph.

I rarely get into 5th gear on the freeway at 65-70 unless I'm travelling long distances, which is rare. And I never use 6th gear at all. (it is a wasted gear unless you routinely drive at 110 mph + for long distances).

And on the track the OEM gearing inhibits fast launches from the tight turns to the straights because it is geared so low.

Yes, this will bring your average RPM up at 65-70 mph, decrease your gas mileage and increase engine wear, but for tight road courses it is IMO mandatory to make the car more competitive. For regular freeway driving it will keep your engine in the power band range of 3,200 rpm in 5th gear.

I'm glad to have found these guys and so close to my house makes it even better.

PS: I need everyones help in locating the Eibach Anti-roll Kit for the SLK320 standard model. It seems they have discontinued the mfg. of this part and is no longer available from Eibach here in the US or Germany. If you run across one during your internet searches, let me know ASAP so I don't have to pay through the nose for a custom sway bar system.
