SRT Front Brake Swap Info
Posted: Fri Jun 29, 2007 4:07 pm
I don't know if you all remember the Camber problems that I had with installing the front SRT hubs/brakes. Well, when i was doing my engine swap I put both the SXT hub (left) and the SRT hub (right) next to each other to see if there were any visible differences.

Well, if you look closely enough the angel of the arm that connects to the struts are ever so slightly different. The chances of them being bent (and at the same degree nonetheless) are slim to none, as there are no stress marking either to suggest anything being damaged. This difference was enough to put my alignment out by 3.5degrees positive camber. After some research and help I came across the following article, which was very informative:

The other suggestion, and the one I'm going to attempt in the near future is to slot the holes in the struts ears that connect to the hub. On my particular struts (KYB) I'm not sure there is enough room on the top bolt hole, so we might slot the lower hole. The plan after this is to get the car aligned and then spot weld the nut of the slotted hole in place so it is less likely to come out of alignment.

This is just my plan so when i get around to actually doing this (need money to get another alignment) I'll do a how-to with pics a specifications.
Comments or concerns are definitely welcome just in case I overlooked something.

One fix to the problem, which the article suggests (not quoted) is Ground Control Suspension Systems, though this is quite expensive.We knew before installing the struts that aggressive camber would be required to make the SRT-4 handle like a real sports car. In stock form, the SRT-4 has 0* front camber and no provision for adjustment. The Mopar coil-overs try to solve this problem with a slotted hole on the strut mounting ears. In theory, this allows you to tilt the hub/brake/wheel assembly inward when you assemble the suspension, giving you instant, free camber. In practice, though, it's nearly impossible to get exactly the camber you want with this system. Manually pushing the wheel to exactly the position you want, to 0.1* precision, and simultaneously tightening this impossible to reach bolt, all without blocking the alignment rack's lasers... well, that's what we call difficult.
To make matters worse, tilting the hub relative to the strut puts the top of the tire closer to the strut, which limits how wide a tire you can use. With our 225/45ZR-17s, we wouldn't have room for any meaningful camber.
