yeah, i would definitaly go with the Tokico illumina's. i've heard from several people that the agx's don't last that long. i'll have to see because i have my rear agx's set on 8 all the time and my car is slammed eve lower now.

hey matt, a 77 280z came into my work yesterday and it didn't have semi triailing arms in the back. did some Z years have another type of rear suspension?

 

If you have the agx's compressed farther than they should be then they won't last you real long. If you aren't droping more than an inch and a half you'll be fine. The beauty of adjustable suspesion is that you can dial in more oversteer or understeer on track days and return it to neutral for the street. My top adjustable 4ways are great for the occasional track session.

Having an open diff will, of course, limit what you can do, but at least better suspension will help you plant the tires.

 

I found a magic setup to eliminate squat. just use your head and be inventive.

Also dont weld your diff. unless you have like 350 horsies and lots of tires

 

Bill, S30 1970- 1978 240 260 280z 's actually have struts in the rear as well as the front..

280zx and 300zx z31 had semi trailing arm.


cronic, you need the ajdustable rear suspension so you can deal with wheelhop with different tire setups and to deal witht he stiffer spring rate.

tokico blues are junk for the back of s130/z31..

you could always put a 240SX rear subframe in the back of a Z31 and run the man setup! That's what my friend Ryan did in Oklahoma! i'll try and post some pics when I'm on my home computer tonight.

He built a bracket to bolt the 240sx rear crossmember, and to also bolt to the chassis of the Z31.. From there, he ran the 240sx OE components witha 300ZX Z32 limited slip, and a custom driveshaft.. The setup is rediculous, now he fits 10.5" wheels in the rear, and the track is about 30mm wider... perfectly flush!!

You should do that.... if you have the time / resources. it will be the cheapest way to REALLY make the car handle and respond well. You'll still be looking at at least 15 hours of labor probably closer to 25-30 to make it right.

 

I think the drop for the AGX's can be up to 2 inches. Mine is at 1.9 right now and my AGX's are wonderful. I've had them for almost a year. Not sure how long they're supposed to last. I do know that if you take care of them and your car isn't too low that the shocks are compressed more than they should be, they will last. Plus, if your car is not too low, AGX's have lifetime warranty.

 

...adding to what everybody has said about the AGX, they don't like to be slammed. I've had my set since they came out for the s14 (about a year and a half?) and threw on some rsr springs a few months ago. They're still annoyingly stiff when they're turned up all the way.

...and $700 IS cheap for good suspension, AGX + RSR is about $650 for an s14.
