This is still a work in progress but everything you need should be in there.

Thanks.

I got the brake lines off ebay a while ago. It came with all 4 and was advertised for the 92-99 Bonneville. The length and fitting sizes were right and the drivers side came with a bracket (like stock) but they didn't fit in the holders where they meet the hard lines. I had to do a little modding to get them to fit. I forget the company name but I do remember hearing of them before and they are located in Canada.

Phenomenal write up....

the springs you currently have....they're for a W body in the front from eibach? I do know that W body springs have a smaller ID than H and C body springs, but I haven't done much research on their load capacity and rates. Your ride height is perfect, I'm looking to do the same thing as mine is stock FE1 ride height. Its ALRIGHT, but really still has the center of gravity too high. I was comparing my car in this picture to yours on the top page of the writeup and saw how drastic the drop was. The only springs that I see Eibach lists for the 1997+ W-body is a set that lowers 1" on all 4 corners. That is great and all, and I really don't think I'd want a WHOLE lot more than that, but my first concern is that I don't know if that is 1" from FE1 or FE2, and the other is that, you mentioned 3" from your stock ride height...are we talking about the same springs? Also...your rear end is much lower than mine as well...meaning its not FE1 anymore obviously, so what did you use in the rear? H body FE2? It would make sense, but it still seems lower than that.

Ride height is good, but a stiff rate is also important...and I'm just not sure a set of W body springs can deliver that...regardless of the fact that the W body weighs almost the same as the H body, the HD capacity generally doesn't seem to be the same.

As I currently have no questions for you on the brakes, you can take that as a sign of how comprehensive you were in that line of coverage. Excellent.

The front springs I have are W-Body Eibach springs. They advertise a drop of 1" but many GPs and the like have seen as much as 2" of drop. I've personally installed a set on a loaded Regal GS and have seen similar results.

The front of my car had about 3.5" of wheel gap before I did the drop. It now has about a half an inch. I think 3.5" is a little higher than a typical FE1 equipped car..

I'm not sure what the front ride height would be on any other W-Body spring (FE2, FE3, etc.) But there may be a slight drop. That's why the one section is just what I know about ride height. I don't know anything else than what I did and I didn't want to carry my assumptions too far.

The rear springs are from coilsprings.com and were purchased as F41 spec stiffness and a 2" drop. I have Monroe Matic Plus shocks in the rear and I can adjust ride height from about an inch lower to a few inches taller than what you see on the cover picture.

The ride with my combination is very nice compared to my previous drop on coilsprings.com F41 spec springs all around on KYB GR2s. It's more comfortable, handles better, the front end doesn't pogo, and it still has a good stance. I also have a FE2 rear sway FWIW.

Don't get me wrong, my car isn't on rails. But, I am very happy with the ride quality and improved handling.

I'll add the rear spring option in the Q&A section when I revise it.
