one user bought 4.44's for an rx-7 from racing beat.

so i got on racing beat and found these, http://www.racingbeat.com/resultset....rtNumber=13016

would those fit?

 

Why not just get Motorklasse 4.44s?

 

i was playing around in the gear calculator and on an ap2 the 4.44's are pretty high. would be a little higher than 4.77's in an ap1. and the 4.3's looked just right.

 

Based on what? Top speed? They only change the Transmission gear ratios 4% lower on gears one through four, Gear 5 is 1% lower and Gear 6 is 2% higher. So an AP2 with 4.77 is better in 6th than an AP1. the only differance is the 1000 rpm less on the AP2.

The 4.44 is 8% higher then the 4.10, where the 4.77 is 16% higher. So if you do the math, an AP2 is 12% higher in first- fourth, and that is still less the a Ap1 with 4.77.

i was going by the turnzero gear calculator.

ap1 at 8900 rpm with 4.77 - ap2 at 8000 rpm with 4.44 - ap2 at 8000 rpm with 4.3

36 - 34 - 35
56 - 52 - 53
77 - 72 - 74
99 - 91 - 94
118 - 113 - 116
142 - 139 - 143

4.44's on an ap2 look pretty low according to the calculator. granted the crusing speeds aren't all that different.

72 mph at 4,000 rpm on 4.3's
69.7 mph at 4,000 rpm on 4.44's

didn't realize the motorklasse were so inexpensive tho, that may not be a bad option at all. especially considering that the speed limits on the highways in my area are 55 and 65, they may help me keep my speed down

thanks for the info
