I have been working with Titan Motorsports to develop an all new control arm setup for my car. They have just about completed the R&D on the front and rear upper control arms and have created a rear toe link adjustment similar to the Porsche GT3 style control arm in the rear. The remaining factory control arms all have custom fabricated delrin bushings.


The F & R upper control arms use spherical bearings at the end of the wish bones to make the arms longer or shorter which will provide camber (and caster in the front) adjustment, eliminating the use of the OEM eccentric bolts to make adjustment. The really trick part on these is the use of Riley Technologies camber adjusters from the Daytona prototype cars. This enables making camber adjustments in a matter of a few minutes that will NOT affect the toe settings at all. So based on pyrometer readings, a few turns of the adjuster makes the camber adjustment…


For anyone who has done their own alignment on a Supra, you well know how long it can take to set the rear camber and toe. The rear uses 2 eccentric bolts to adjust both of these aspects and those bolts have to be torqued to 134 ft/lbs, which means that when you are setting toe to a 32nd of an inch, you have to slightly overshoot your target so that when you torque the bolt it brings it to where you want your setting. In the past this has literally taken me hours of back and forth some times to get it perfect. With the toe link adjuster, once the camber is set from the upper control arm, it is just a matter of turning the barrel adjuster and setting the toe…nice and easy and VERY precise.


One of the issues I was having repeatedly was the failure of the front lower control arm bushing on the right side of the car. We think we traced the problem to the excessive heat in that area, as the turbo, wastegate, and downpipe are there and I am using a greddy wastegate the has the small dump tube to the atmosphere right there as well. With the delrin, we don’t expect any more issues.

Nice work!

 

We've been thrilled to be a part of your project, each time the car comes in its another evolution in its sucess.

 

Sounds Very Nice.... If Titan's making them, they'll be first rate.
BTW, Thanks for the Big-*** Sways back in '05 (thru JP Imports).
A few questions;
1. How streetable?
2. How soon?
3. How heavy/light compared to stock?
4. How MUCH?
Thanks;
Will

 

We expect these to be in the $1400-$1600 range. We should be making these in 10 weeks and plan to stock them and offer them. They are very streetable, Joshua's set used Delron and is streetable, if there is a future factory bushing replacement that comes out we'll be able to use that bushing also.
