Need Suspension Guidance
This is exactly the thread I was looking for, thanks alot for the info. But I have to ask which shocks you went with? Did you use all stock replacement from bilstein Heavy Duty Series (R30-5014-H0) Front (34-050149) and Heavy Duty Series (B46-1214-H0) Rear (24-012140). Or did you go with the 3KGT for the Front Heavy Duty Series (R36-5022-H0) Front (34-050224)? And for your rear strut mounts, are they from the gc Coilover Conversion kit, 86-92 Mazda RX7? Did you have to modify them to fit the bilsteins?
Good, I'm glad it was helpful. I went with the regular Bilstein HD shocks from TireRack for $476 shipped. They were listed for an Rx-7, not the 3000GT. The Ground Control 86-92 coilover conversion kit does include the rear strut mounts and I didn't have to modify the rears at all, the GC sleeves slipped right on and stopped on a small lip on the shock body.
No problem man, happy to help. I did my best to document everything step by step hoping that someone would benefit from it but let me know if you have any other questions.
I got both end links off today, only to find out that I couldn't get the rear sway bar out without removing the suspension, removing the catback or cutting it in half (which I'll probably end up doing since it's trashed anyway). So I hooked the straight one back up and took the car out but I don't like it yet. When everything was done the car dove the same, just faster and felt way better. Now it acts differently so I have to relearn how to drive it but I was able to carry a bit more speed through turns and when I was ready for the rear to slide, it didn't. So I know it'll be faster but it's gonna take some getting used to. I'll update again when I get more time behind the wheel or turn the plates and correct the camber.

Time for an update since everything is pretty much done with. Got the car aligned, went for a hard drive, everything was great until I heard a knocking noise up front. Turns out the nut on top of the driver's side strut was loose. No problem, except the car was put on a lift before it was discovered and tightened so the alignment got thrown off. Back to the shop.
My camber that had previously been -2.5* was now -3.04* and -3.17* but I didn't change it since I was trying to get out of there. I guess the suspension settled? The tow was set back to zero, I had a hard drive last Sunday and I autox'ed the car this past Sunday. I set my tires to 40 psi front and 35 psi rear based on some recommendations that I read, coming from 32 psi all around. I spun the car once and didn't like how it handled so my last run I dropped my front/rear hot pressure from 43/38 to 37/32 and took 3 seconds off my fastest time, 5 seconds off from my first run. I'm very happy with the car and I can't wait to get these six year old Bridgestone RE-01R's off and some new RE-71R's on.
