getZ Posted September 28, 2006 Share Posted September 28, 2006 I personaly only run a 225 50 16, but I have heard of guys running 235 getting them tucked inside the wheel wells without coilovers. I have set of later 280z hats with arizona z car springs and my car sits about 2 inches higher than the back wheels so your springs must really be low. You can also run a spring spacer if you can find one that fits, but your springs probably need to be replaced if you are sitting that low. One word of caution, if you change your ride height that much your camber will be way off for daily driving. Although it may give you a better tire contact area during a launch depending on how the car squats when you take off. Quote Link to comment Share on other sites More sharing options...
crazy canuck Z8 Posted September 28, 2006 Author Share Posted September 28, 2006 My problem must be very week springs because i have 2 inches of clearance but when i put 400 hp to the rears it hits hard.Your Arizona springs are a stock replacement?I'm looking for a quick fix,last races this friday night,new suspension over winter with the group queife buy,i hope.

Nealio240z Posted September 28, 2006 Share Posted September 28, 2006 Use 280zx (2+2) rear springs.. They are for a 3800lb car. I put them in all 4 corners and it lifted me up to the top. Very stiff springs. They do the job well and only squat about 2" under acceleration... Keeps the handeling stiff also... Quote Link to comment Share on other sites More sharing options...
getZ Posted September 29, 2006 Share Posted September 29, 2006 My spring rates are 200lb at all four corners, but I'm still sorting out the car yet and haven't really made a strong attempt to dial everything in yet. Here is Arizona the race season is just beginning. I haven't bottomed the suspension out from a launch but I'm still breaking in the motor so I'm still kind of taking it easy. With out both tires spining getting traction is tough. I landed up installing a limited slip from precision gear and it works well, but you need to get the r200 with the bigger ring gear bolts or make a shim for it. I've seen 1.6 sixty foots with several combinations of springs from 200 to 275lb spring rates on z cars so I guess it really depends on the rest of your setup and how good the track is that day or night.

crazy canuck Z8 Posted September 29, 2006 Author Share Posted September 29, 2006 Thanks for your help,over the winter i'm going to change the springs,but i fixed my problem for friday racing.I made a 2" spacer to bolt onto my cap with 3 new bolts welded on top,dropped the springs bolted on and it seemed to work really well.had some big launches now i hope i don't break anything.Will do the first nitrous run tomorrow,wish me luck.
