What are your and the group's thought about non FX3 if going coilovers and just get rid of the FX3?

I don't know if any installation benefit or just avoiding future problems and cost.

Thanks for sharing.

Craig,

Keep FX3 definetly! Keep your ride quality.

I've driven another Z with Morocco shocks and make the car even "tighter".... (though expensive)

Keep the FX-3 works great with it

I would have to agree with the others who suggested retaining FX3. As long as the car is going to be street driven I would stay with this setup. I do suggest that you carefully think about what spring rates you want to run though. If the car is street driven I would go no higher than 425 front & 300 rear MAX. Randy talked me into 250 rear and I think that will be a good choice. YOu might even consider less if it is a later model car whoose springs were a tad softer than the early. NOthing would be more disapointing that being unhappy with too stiff of springs. So far in my short amount of driving ( just settling ride height) the car feels great. I hope my resolution to FX3 problem is quick as I have never had this issue before the install. I have to say that the squirly side of me justs LOVES the stance of the front now. It looks serious. Now I need to spend the same amount of time on the rear and then off to the alignment shop. Its funny I don't know if I am more happy or releived that this is done. It does give one a good sense of accomplishment though. I very lucky to have some good friends who really helped me out.

All,

Thanks for the confirmations of staying with FX3. I'll check with Randy about spring rates and I may not have a choice with the group buy.

Mike,

Your setup looks great with the photo that Bob posted and that is kind of what I am after in terms of looks, ride, and handling. My setup came in the last week, but I was out of country and finally looked at them today. I got the whole deal with trailing arm and camber brackets; everything looks great and well packed for shipment. The front rates are 425 and the rear 250 so Randy felt the same based on what I was looking for. Here are his thoughts: 300 too stiff, 275 right on, 250 a tick softer than the 275. I'm waiting on Carter brackets and in the meanwhile I need to figure out how I will have the shocks grooved. Thanks for sharing your info and experience with this setup.

Craig

GOLDCYLON · 02-08-2013

Craig I wholeheartedly agree.

http://www.zr1.net/forum/showthread....ight=coilovers

As you can see above I went with the hypercoil 425/275 spring rate as well which is the right rate for our car. Any stiffer on the back end and you will feel like you are riding on a buckboard

After the install im sure your impression will be the same as mine that this was the way the car should have been setup from the factory. In turns she will ride like on a rail.

XfireZ51 · 02-08-2013

I re-did my setup last year using 400/275s. I am using Moracca valved Bilsteins
and did a full replacement of the front bushings w poly. I have thought about going w 300 in the rear. The taller 19" Z06 wheel on the right rear will rub slightly on the inner part of the wheel well when hitting some dips in the road.
Another solution might be to use a slightly thicker spacer on that side to push the right rear tire out further matching the positioning of the left rear. As we know, the left/right wheels positioning is not symmetrical on our cars. Right side is slightly shorter than left.
Overall, I really like the feel and ride of the coilovers. My preference is for a tauter, tighter ride. I was one of those crazies that actually liked the Z51 setup on my 84. 200# lighter than the ZR w 11" rubber on the back and C5 brakes up front. Handled very nicely.
The poly really tightens things up in terms of road feel and transient response. Not a Porsche but much better than stock. I usually am on the SPORT setting for daily driving. Al drove my car and really liked the setup and felt it was a better feel than his stock Bilsteins.

Daryll,

Thanks for sharing your thoughts and link. I can't wait to get these on. Not sure how much difference the 250 in the rear will be and I might like it a tad bid softer so we'll see. Thanks again!!
