Eibach Spec V Front/Rear Sway Bars Testing!!

[SentraFi]

I was at Willow Springs Raceway in California at the Big Track on Saturday.

Man, what a rush! The Eibach engineer, is the best driver I've ridden with. He showed me what my car can do in the hands of a professional driver. The highest speeds he did was one turn at 90MPH and exiting another at 115MPH. My car always had the secondaries open when he was driving. It hugged every turn, even on stock tires! He drove it twice and concluded that the rear prototype sway bar needs to be stiffer.

When I drove it, the car felt flat in almost all the turns. I was hanging with the Corvettes in the turns Then they blew me away on the straights Here's more in Dragrace/Autocross/Rally Discussion.

I saw Mike Kojima (aka SmartBomb) there and he saw Dave drive my car. He thought the car looked flat in the turns and it looked like it handled very well.

The sway bars are tubular, i.e. bent, round rods. They will be powder coated red. The rear bar is adjustable by sliding the sway bar in or out to adjust stiffness, then locking in place via bolts. The front cannot be adjusted due to space limitations. The front bar replaces the stock one.

The price is not known at this point. Tentative release date will be around 6 weeks from now.

The spring rate of the Eibach Pro-Kit Springs (Part No. 6362.140) is higher than the stock springs on the Spec V. I’ll email him asking what the stock spring rate was and then you can compare it to the Pro-Kit.

It has been tested on a Spec V with Pro Kits installed. You can you use these with the stock springs.

These bars will make the suspension stiffer than the stock ones.

I do not have any experience with the Progress sway bars so I cannot do a comparison.

The front sway bar did not accentuate under-steer during the test drive at Willow Springs. It may have been necessary to change the front sway bars to keep the car balanced.
