Carter, I've admired your work for some time, but thanks to David's link I see that the relocation is at the frame. My issues are at the end links. What I need should be easy, two "U" shapes with threaded rod between (like a turnbuckle), but I have not yet been able to find the right types of hardware in sizes/specs that my noggin can decode.

Thanks, guys - and enjoy your CO kits - pretty cool you can do that and keep the FX3 too. I'd keep an eye on the rear lower pin though, single shear and potholes could be a concern with the shock mount now the load path (where before it was just damping). It is pretty stout though and this is an old argument without much evidence of failures that I've seen.

Best,
- Jeff

Batchman,
You are welcome and thanks for the kind words. If you need anything machined or custom made keep me in mind.

Daniel, Daniel, Daniel...........why are you doing this to me? Let me think about this great deal. I have been wanting to do this.

A DRM prepped LT-1 car ran the slalom at 72.1MPH....when you consider a ZR-1 has bigger rears.......I am guessing a properly set up DRM set puts you pack in Supercar handling territory

Just thought I'd add a link to a recent conversation about coilovers.

I'd love to get in on the GB it sounds like a great deal, but I've already well spent this years budget!

I did the poly front end this year. Replaced upper and lower ball joints also. I don't think about the steering now. It's something I just assume. Tracks great.
Some suggested the poly would cause harshness. I think it makes everything tight.

I agree with Dom. My car has the DRM Coil-overs and poly bushings. I bought it that way and got lucky. The ride is firm but not harsh. There is not a rebound feel or any bounce when hitting a dip in the road. Just a firm feel. I'm really surprised at how nice it rides, for my taste.

Craig, I have already made a call I am going to see if we can do something for you. I'll be in touch.

IDK about LT1 but our L98 car gave them hell at track days with this set up. We would get dusted in the strait but the corners were a different story. Add some Hoosier slicks and 315's and the car is phenomenal.

I would have to agree the poly doesn't make it harsh at all and really makes the car feel tight. The Z has 78K on it and as far as I know has had poly since day one it’s held up great.

Too bad I live in a place where coil overs are just not ideally suited to the roads.....okay so now I'm wondering if I select the right spring rates for my road conditions will I have a 'liveable car'????? I have no idea how to go about determining what spring rate would be suitable for mostly broken, and abused road surfaces. Anyone care to point me in the correct direction?
TIA

Tom,

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
