    If that's the way they are, I'm ok with that. Just trying to improve what I can. Thanks

    Thanks for the input, I appreciate it! So what amount of camber front& rear do these cars like? Stock on the front looks pretty straight up and down, maybe a little positive.

    I got some more work done to the car yesterday. Put in the new O2 sensor, and hooked up the AP. Downloaded a mild 91 tune and took it for a drive. It's running pretty good. More come....

    Peak lateral grip will be found somewhere north of -2.5° camber. You'll have to do some testing to optimize it front and rear.

    Ok, I'll be ordering the adjustable upper ball joints, then start playing around with it. I used to work at shops where I did all the alignments, now I have to pay for them. I might have to get my own setup, and save the hassle. Where I live it's 200 bucks for an alignment!!

    I thought I'd give an update. Been working nightshift for the last 14 nights, it's been raining non-stop here..... The car has been working flawlessly. Great power, fuel mileage, the AWD in the rain is fantastic! So many people that I talk to are really impressed by the car.
    Still waiting on more parts to show up. @phate what info do I need to gather to start picking out shocks and springs/coil overs, and swaybars?
    Also wondering on tire/wheel combo, and fitment?

    I would start by getting corner weights for the car at race weight (with driver in it, as much fuel as you would run with). From there, you can calculate spring rates based on sprung mass frequency (I'll break out my spreadsheet since it was lost to the public when MSF went down).

    Wheel/tire - you can fit up to a 335 on a 12" wheel :) Just depends on how much you want to cut. With a good roll/pull, a 255 on a 9.5 +43(ish) is a good fit.

    Ok, I'll figure out a place to get the 4 corner done. Nope, not ready for the chop shop yet..... Though I'm sure I would like the handling!! Right now the first step will be 245/40 ZR 18's. Just because that's what I have to sort it out. The poly bushings, ball joints and shocks/springs will be at the same time.

    Hey @phate, where did you get your scales from?

    Friend of a friend, who bought them used to begin with. Scales are very hard to come by second hand...

    Hey everyone, I haven't posted in awhile, here's a bit of an update. I had the car working really well, started the tuning with Will @ PD Tuning. Which is Great by the way!! Getting the logs sorted out, quick replies, and adjusting the tune. The only thing, the clutch wasn't happy with the extra power.... So, looks like I'll being pulling it.
    I picked up an ACT 6 puck assembly, changing out the original clutch master, looking into the Speed Performance shift forks. I also picked up a CS rear diff mount, and a Sure Motorsports front diff mount. I know the Sure ones aren't the greatest, but the stock is definitely crap! Also found DSS 500hp axles.
    The car has been sitting for a few weeks now, and will be for the winter, I'm building a C-class motorhome at the same time. The MH has taken a lot of my time lately. It's all custom interior, and completely off-grid if we choose. It'll make a great tow vehicle for race weekends too! That's it for now.

    I started doing some work on the car again. In between fixing everyone else's vehicles, working on the house, Covid survival mobile.....
    Also building a car trailer. So, I guess I've been busy.
    I'm prepping the rear diff mounts, axles, I also picked up the Siberian Polyurethane bushings. The axles that I got are used, but one of the inner boots was rubbing on the swaybar bushings, and needs to be replaced. Does anyone know what size I can order for a replacement?

    I'll post some pics in a couple of days to show the progress!

    I had to rebuild axles for my Starion years ago and I just took the axle apart then went to a local parts store to match it up to whatever ones they had there. Turned out to be fairly cheap as I only spent 30 dollars to reboot two axles.

    Nice! I'm trying that route now. So far all we're coming up with is the Driveshaft Shop boots. Hoping for a cheaper, local source!
