I finally found the time to work on my car yesterday. Got my Carlyle racing 15” conversion spindles and brake kit on. Going to align it today.
I know! It was dirty.
No, it all went pretty smooth. I did have to do a little more grinding after my initial test drive. Hey CI, are you running coil overs? What kind?
Mine went smooth too. I’m running Viking DA Crusader Coilovers in the rear. On the front I stripped the springs off the coilovers (due to the springs hitting the upper control arms) and went back to a stock transverse spring, along with the bare Viking DA shock.
Me? I’m running Hoosier P275/60R15 (17375DR2) Drag Radials in the rear and M&H MSS017 Front Runner, 26.00 x 4.50-17 (165/70-17), Bias-Ply up front.
So give or take your running a 28in in the rear and a 26 up front.. Any ABS or traction control issues or lights on?
I ordered my Carlyle 15" kit today and was curious if there way anything to mention or a way the rear of the car should be aligned afterwards? Is the factory specs and tolerance a good place to start or something better for the track?

Yes, I’m running an actual 28” dia rear with a ~26 dia. front tire. I’ve never had any issues with ABS or traction control.
The way I aligned my car was with very close to zero toe in, mainly because I’m using spherical bearings in the rear.
As far as camber goes, the ideal is to adjust it so that when the car squats on the launch, the rear tires are sitting perfectly flat on the track surface,
So, in order to simulate that squat, I raised the front of my car in the air a bit (using the two front arms on my lift) with the rear tires sitting on Race Ramp 12” tire blocks, to load the rear suspension whilst giving me space to get under the car.
Then I adjusted camber to zero degrees and checked toe in at the same time.
For those who say that Corvettes don’t squat:
Have any of you needed to install rear bumpsteer kits with the 15" conversion or is there special alignment adjustment that needs to be made, I've had mine re-aligned to factory specs but still doesn't feel a stabile as the factory spindles did. I wonder if a little more toe in would help or zero camber out and/or check compared to front bump steer any feedback would be much appreciated!

Pretty sure when I had alignment done they took to much toe out of the front, I thought it felt better when I aligned it cause I never touched the front. I've been seeing you on here for years, to me your a legend, Thank you for the reply I am honored, by chance does it make a huge difference? are you running them? I really need to travel the suspension to see how much the toe changes, You still in Indiana? I'm in NWI Thank You Brother!
