jmeris Posted January 23, 2012 Share Posted January 23, 2012 I love it....a reply to a post....7 years later!!! Special Projects no longer carries SRR. Instead, they carry a MUCH better quality final drive brand: GEAR-X Quote Link to comment Share on other sites More sharing options...

H4CRXSi Posted January 26, 2012 Share Posted January 26, 2012 Edmond, I can help you with this, just need to know what size/brand of tires you are running and also what your rev limit is. After that, I can tell you what your top speed will be with both a 4.9 and a 4.73. Regards, Sam Quote Link to comment Share on other sites More sharing options...

H4CRXSi Posted January 28, 2012 Share Posted January 28, 2012 Edmond, If you are running either the 205/50/15 or the 225/45/15 then your tire diameter will be 22.9". With the factory rev limit of 6800 rpm, you will top out in 5th gear at 123mph with a 4.9 FD and 127mph with a 4.73 FD. Let me know if you have any other questions.
