The DDMWorks Cross Bay Brace is designed to reduce flex by tying the two parallel shock towers together. This transmits the load of each shock tower during cornering, sharing the load between both towers and reducing chassis flex. We did torsional testing here at the shop with one of our test cars. The procedure that we followed was very similar to the testing that we did with the backbone, and was as follows:
1. We started out with no brace in place and put the car on the lift so we could raise and lower onto jack stands.
2. We then lowered the car onto 3 jack stands, 1 jack stand was located at the drivers side front suspension pick-up point, a 2nd was located at the drivers rear suspension pick-up point and the third was located at the passenger side rear suspension pick-up point.
3. We then used the jack and lifted the car by using the passensger's side front suspension pick-up point. We took a measurement of the distance between a fixed point on the car behind of the front wheel and the ground, and made note of it.
4. We then used the jack to raise the passenger's side front until we could move the front jack stand, and then made note of the distance that we had to jack the car.
5. We then repeated this process several times to get a good range of values and make sure that they were consistent.
6. Once we took these initial measurements and had a good average of distance to lift the car, we then installed the cross bay brace and repeated the whole process above.
The results:
With the stock piece in place, it took an average of 12.3 mm to raise the car off the front jack stand. Once we put the cross bay brace on this average dropped down to 10.2, which is a 15% improvement.
Fits: 2.0L Solstitce GXP, Sky Redline and Opel GT**
Fits: 2.4L Solstice, Sky * **
* 2.4L's will require an aftermarket intake for proper fitment, does not fit with stock intake.
** Installation of the brace does require the removal of the plastic engine cover and also the relocation of the power steering reservoir. Some trimming of the plastic wheel covers is required for installation.
