In thinking about this when you say "not ideally suited to the roads" are you worried about harshness with bumps or the lower ride hight? The roads were I live suck (for the lack of a better word). The ride hight is all that I worry about going down the road. I have them cranked pretty low so that is my problem but it is fully adjustible so if you wanted you could crank them up and have a stock ride height or almost stock. Maybe talk with DRM about a different spring combo? I use Michael Eddy at HRP World for the springs on the track car and have played with different rates. I ended up back with the ones that came with the original set up :censored:

For the 89 Track car it is 400 front 275 rear I went as high as 500 front and 400 rear it "felt" fast but my lap times showed differently also it wore the tires much quicker. The ZR-1 is running the same as you 425/275. All were hyperco springs.

Daniel,

Thanks. I think you meant about the shipping? I have a California zip code so same like shipping in the US to my military address, but it will have to be USPS.

It is FPO, AP 96347

Depending how big and the weight of the box, parcel post would be lowest cost as I don't imagine it fits even in several priority mail flat rate boxes.

Daniel, thanks for your time on this.:thumbsup: It's both! Even stock you have to very wary of where you intend to drive to escape to somewhere that you'd like to drive! And that's with a stock ride height!

I am grateful for the advice. I'm just going to go with the brackets. The volume never goes down, so the wear never gets less, so the repairs never cease. You should see how deep the truck ruts get before they get repaired! Never mind all the other stuff.:sign10::cry::sign10:

:cheers:
Tom

Daniel, after reading some of the installation info, I am concerned about one issue. Did I read correctly that you could not adjust the ride height on the rear without removing the FX3 connector. I have non fx3 on my race car and height adjust is not a problem with just using the spanner wrench. I am concerned about this issue. It would seem to me to be a big problem weith setting the ride height then. Am I confused or am I not reading this correctly. Please give me you feedback as I am looking to jump on this coilover group prchase as well. Thanks!

Not true. I adjusted my ride height w a spanner after having installed the coilovers. The one issue I had in the rear units was positioning the springs so that they cleared the half shafts. The springs sit asymmetrically and can be rotated so as to provide enough clearance.

A complete falsehood. Im running the FX-3 and the DRM coilovers on all four corners on my ride. It took a few adjustments on the rear as well before I was satisfied and the FX-3 system was connected the entire time. GC

Dom is correct space is problem also with the original Dogbone trailing arms which is also why most of us have upgraded the trailing arms to the Banski Heim-Joint trailing arms.

Some suggested the poly would cause harshness. I think it makes everything tight.

Yep I did Poly eveything and replaced the uppers and lowers. Its not harsh its mega tight as Dom Suggests.

Here is my thread on the project. I just reloaded ALL the photos on that project.
