I may be barking up the completely wrong tree here, but it's worth a shot.
I have a 91 Notch 5.0/T5. Recently went through an extensive body restoration. Upon getting a few things ready for the local cruise, I noticed the suspension was all but shot (broken front coil spring, broken sway link, frozen control arm bushings, etc). Replaced everything with Moog parts for now.
The transmission output shaft seal is leaking, as well as the differential pinion seal. The clutches in the rear end are completely gone. Thus, the rear end is coming out this winter at a minimum. Plan on re-painting, FMS rear cover, 3.73 or 4.10 gears, and GT500 clutches for the posi (stack changed for more friction).
Ideally, I'd like to have a decent street/strip suspension that won't drive like complete E36 M3 on a country road. I don't expect it to be anything near my Z06 in any regard. The goal would be to make the car decent in a straight line, but not a horrible handler. It is to be primarily kept at our cabin in northern MI, so the ability to take on some spirited country road driving would be preferred.
I have SFCs from TeamZ (local drag guys, they build quite a few high $$$ Mustangs). They actually go through the floor and have torque-box reinforcements. Seemed to be a good compromise between the Maximum Motorsports setup and the Griggs World Challenge stuff. EDIT - looks as though these will cause issues with the carpeting. Looks like MM it is.
From my understanding, it is the best compromise to go with Poly lower bushings with the stock rubber upper to keep the rear end from binding. Was thinking something along the lines of these and replace the uppers with stock rubber bushings? Or, even keep stock uppers with the Team Z or MM lowers? EDIT - Seems the MM kit is the "easy button" here as well. From my reading the MM lowers, a stock upper w/spherical bearings and MM Panhard seems to be the "hot" setup here. Will it hook decently in a straight line?
Also going to go with a MM K-Member/Strut tower brace and either MM CC plates/bumpsteer kit (probably will need outer TREs in near future).
Brakes seem to have a myriad of options. Long story short, I'm looking to go 5-lug later down the line. Thinking the Cobra setup (13" PBRs dual-piston front/11.65 single-piston rear) would be an off-the-shelf solution. This would be used in conjunction with a 93 Cobra booster and SN95 MC/Spindles with a Wilwood adjustable prop valve. Or, I could to with a complete Wilwood kit and a smaller rotor. I feel keeping OE-ish parts would make it a lot easier for servicing on down the line. For starters, I plan on refreshing the stock brakes and going with HP+ pads up front for increased "bite."
Am I too far off in thinking that going with this sort of setup would allow for decent handling, but still get the car to hook in a straight-line? One of the main reasons I've considered TeamZ parts is that they are manufactured locally, and a lot of the drag guys I know run their stuff with great results. I figured that while drag-oriented components, their quality is much above UPR or eBay brands. Most of that they make is 4130 chromoly, so I'm not worried about durability as much.
Car is pretty stock in the engine department, minus MAC exhaust and a CAI. That will stay the same for the time being. Later on down the line, it will get an LS or "built" Windsor when funds allow. It's plenty fun with the anemic 5.0 for now.
Thoughts?
