Datsun Roadster Suspension Help?

Recommended Posts

Just bought a 1966 Datsun roadster roller with an SR20 engine and 5 speed. Looking to upgrade the suspension. Would like to go independent rear suspension. It's been suggested to use the RX7 gen 1 rears.

Anyone know of someone who builds or sells kits for upgrading the suspension?

 

The 311 Forum mentioned a Lou something from Australia, but it was a 8 year old post. Not sure if he is still in business.192.168.o.1 192.168.0.1 tp link login

 

Thanks in advance...

Gen 1 rx7 is a solid axle.  It is a great axle but its not irs.  Duncan has one on his 510 wagon.  Narrowest irs that would potentially offer an actual upgrade in performance is a miata.  Its about 6 inches wider than the roadster.

 

Check out Bob3's Misinformation build.  Its a miata swapped 411, which frame and size wise is very similar to the roadster.

Actually, I do not.  I'm pretty sure Just Joel does, but not 100% sure.  I recall seeing that swap featured on Michael Spreadbury's site a long time ago.  I don't know the name of the site, but shouldn't be too tough to find.

 

Edit: I remember it was Spriso Motorsports was his company's name..
