I have an '86 NA 13b and trans in an Austin Healey Sprite. I need a stronger rear end. The AH unit break under much less HP. Which LSD live axle RX-7 rears would give me disc brakes that will fit inside 13" wheels? The rear will have to be narrowed. Also interested in any advice on rear suspension for this set up.

 

81-85 fB rx7 gsl are equiped with rear disc and 13 inch wheels. 84-85 gsl-se also have rear disc but come with 14 inch wheels...

For suspension, how much room back there for a 3 link setup and equal length watts link?

 

Thanks for the info on the 81-85.

 

No experience with a Watts link set up. Was thinking of 5 link with a panhard.

 

Your welcome... Post pics of your car asap.

Thanks,
Dwayne
