I finally had the front and rear K-Mac camber bushing kits installed. My car is lowered on H&R VTF springs up front with new 245/35 19 Michelin PS4s on 8.5 x 19 +30 offset and H&R Sport springs in the rear with 285/30 19 PS4s on 10 x 19 +55 offset.
This was my alignment before the kit was installed. Went through a couple of front tire sets in more or less 12-15k miles with this alignment.
I was able to achieve rear camber settings by elongating the lower control arm holes to be able to pull the arms in. It was only limited by the amount of toe that could still be adjusted before going out of spec.
These are my new specs after the kits were installed.
The additional adjustments for caster helped a lot with the slight pull. Initially had over 1° difference left and right after install. Front camber is now within OEM spec. The rear camber can now be adjusted below OEM specs to allow more contact patch for the rear tires.
So far so good… Really happy with this set-up.
Drive in good health everyone!
@mo11 It's been a year. How do you like the kmac bushings? Any autocross or track time with them installed? Thanks.
So far so good! No autocross or track for this car… Just a regular daily. I installed the kit just to get more longevity on my tires. The handling is still ok, but if I could afford to replace tires every year and a half I’d probably have the camber a little bit more aggressive. Maybe -2° up front. However, I’d keep the rear settings the same.
As for the alignment… still runs straight, tires are in good shape, no complaints. 👍
