Show your stance (round 2)
« on: May 02, 2021, 06:02:58 AM »
So the old version of the thread was really helpful for me so I thought we should get it going again.  Please post a picture with your suspension upgrades, rim and tire info. Any fitment or ride issues too.

Not the best picture but the only semi side shot I have on my phone.





Pro touring F body G rear leaf springs set at lowest shackle setting ( I need to raise the rear about an inch).
Solid body mounts
PTFB subframe connectors
Hotkis front 2" drop springs.
17 x 9 new version snowflakes
Basic KYB shocks
Tires, front BFGoodrich g-force Sport Comp 255/45/17
Tires, rear " " 275/40/17

Only ride issue is the rear end seams to be bouncy over woops (hard to explain). I have been told that it could be from the rear shackles set at the lowering hole (top hole). So we'll see how it rides when I move to the lowered hole (which raises the car).

Nothing special with mine. Car always sat high since I bought it ten years ago. Last year I finally replaced control arm bushings and decided to cut the springs that were in there. No idea what they are. Just lowered the rear with 1” blocks. Could use a tad more maybe. Poor mans way to lower lol. First pic is before, second two after. Just 255/60/15 tires.

Mines always been a little bouncy in the rear too. Better with the new shocks I put on but still there. I always thought that was just a product of a leaf spring setup.

Are you planning on changing your tires? They look good. The whole setup looks good.

No, I just couldn't remember what they were.  Updated now.

I still have to get my wheel flairs on.

I just recently got my springs sorted out. The car sat way too high when I bought it and wanted it lower since day one. One of the first things I did was swap out the rear leafs with a set of stock height from Classic Industries. https://www.classicindustries.com/product/*rl12.html
I was under the impression that stock height would be lower than what was on the car but they weren't much of an improvement. This is the challenge in picking out springs, what really is stock height?

When I redid the front suspension I bought UMI lowering coil springs from Summit. https://www.summitracing.com/parts/upi-3050f
I believe the spring rate is 600 lbs on these vs the stock 300 lbs and put the passenger side right where I wanted it. For some reason the driver side ended up 3/4" lower than the passenger side which was too low, and yes they were both seated properly. I ended up putting in a 1/2" spacer on the driver side which evened things out nicely.

To deal with the rear, I had my stock height springs re-arched. I originally measured out a 2" drop for the rear to get the body line perfectly parallel with the ground, but was concerned about clearance. The spring shop and I settled on 1 1/2" drop to be safe but when I got them back it was actually closer to a 2" drop. The downside to re-arching is I'm stuck with the stock spring rate of 126 lbs. Just this last week was the first real road test so I'll find out soon if I will have any travel clearance issues.

One faux pas was that my measurements were done on an almost completely empty fuel tank. My first road test was to the gas station where I filled up the tank and lost about 1/2" of clearance. It turns out that 1 1/2" drop would have been a good target. But for the most part, I'm happy with the current height.

Photo below of the current stance. Wheels are 17x8 in front and 17x9 in rear. Tires are 245/45/17 front and 275/40/17 rear. I also need to put my wheel flares on along with the front bumper.
Also including photos of before and after the re-arching.

1977 Close to stock. Original leaf springs, original style shocks, 255r6015 tires on 8 in snowflakes (non original). Poly body bushings. Original front end components and springs as far as I know.

Car rides nice, a bit bumpy but no handling problems. No tire rub with the oversized tires. Tires are a generic brand which is the only set of 15" tires the shop had in stock. Would I use them again? Yes have had no problems and the price was ok. I go to shows but none that care if I am running original brand name tires.

Never did upload a photo in the old thread because i have 80's wheels  :lol:  but ill upload one mostly for future reference if i go to another 17-18" setup.
I am currently looking for a setup, but i am particular about what wheels, and it will most likely not be a traditional hot rod type wheel.

Current suspention Ridetech dualrate front springs, bilstein shocks all round, rear leafspring i dont know too much about but guessing an aftermarket variation with drop.

Front tire rim 7x15 ET -7 with 225/60-15  Rear tire rim 15x8 ET -30 with 245/60-15

Is everyone else having problems with tires not being in stock?
I decided to go with 17" rims to allow for 13" (6) piston calipers and
was looking to buy Nitto tires to complete the package.
I've called Nitto several times to no avail, there using the CCP virus
as an excuse. Not a lot of options out there. :-(

I went with these ultra high performance from Tire Rack - https://www.tirerack.com/tires/tires.jsp?tireMake=Sumitomo&tireModel=HTR+A%2FS+P03&frontTire=445WR7HTRASP03XL&rearTire=74WR7HTRASP03&vehicleSearch=false&fromCompare1=yes

They appear to be in stock (for my sizes) but with Tire Rack you have to put in your zip code because they ship them to you so don't know how much location factors into the availability.

Gene,
I was thinking about Nitto tires, 285/40ZR17 REAR TIRES AND 255/45ZR17 FRONT TIRES. Both being around 26" tall
Similar to what Tom has on his TA.
The builder is waiting on tires to make measurements on the DSE 9" diff I'm putting in.
Thanks for the input.
Darryl

Has anyone here had their aluminum mags widened? Have you had any problems with them?
I have some 17"x 9 1/2" TA mags  that I'd like to open up to run 315 rear tires.
I've been looking at a company, Weldcraft in MI. Haven't got a quote yet.
I'm thinking about 11" wide rims.
Thanks,
Darryl

Let's try to keep this just a post of a picture of your car and what suspension and tires you have. It was nice to look at the old thread and find what stance I wanted and what suspension parts to purchase to get the look I wanted. If you have questions, start a new topic.

Thanks!
