1999 WS6 convertible approx 4000lb race weight!!!!
LS1 Motorsports Turbo with hopefully 600rwhp/600-700rwtq.

I currently have a Moser 9" with 4.10 gears.
It is a 6 speed.

I was running 11.70 119mph with my ARE 378 last year with the 4.10s and was going through the traps @ approx 6300 rpm.

I was thinking 3.30 or 3.50 with the huge torque this thing will be making.

Any Thoughts?

 

Keep the 4.10s and run a 28 inch slick at the track <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> That would be the best matched combo for your application at the track IMO

How high do you buzz the car and are you looking for the best ET possible or just some okay times?

If you want max ET you need some sort of 28" tire.

 

I agree with Chris. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

28 inch tire and 4.10 gears. <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

I am interested in good track times but it is not my main priority. What would be best for my dailing driving with 275/40/17 Drag Radials and weekend trips to the track.

I have 11.5" wide ET streets mounted on 16" rims.
I think they are 26" high for the track.

 

I would still keep the 4.10s. Run DR's on the street. The 26 inch ET streets wont have a prayer hooking. Need full 28 inch slicks...
