What do you have for chassis stiffening? Options

[Justinp71]

I put some more horsepower in my car, so far I have just autocrossed it on street tires. I have the bolt in roll bar that has the mid bar going to the floor.

Besides that my chassis is stock and I am wondering what I should do for more re-enforcement... so I can comfortably run on slicks.

Below is a photo of the roll bar. I don't consider the roll bar to give to much chassis stiffening, but it just might help with cracking the longs.

Edit: I mainly just use the car for street and the occasional Autocross or DE

OK I guess maybe I should not be voting since the only runner of the 4 914s I have, I may have just sold. But I figured I would weigh in anyway. My 914 that I used to auto-x with had no chassis stiffening. I had upgrade suspension and ran on sticky DOT tires. My friends 914-6 (conversion) that I ran once at Thunder Hill and once at Button Willow had a 4 point cage, rear chassis stiffening kit, stiff suspension and wide tires. Latter when he started racing the car (PCA Club and PRC events) we had to tie front and rear suspension to the cage and add re-enforcements to the inner rear mount since they were cracking.

I am planning on adding a cage to my next 914 track car (which ever one that ends up being).

Well Thanks for posting anyhow Jim!

When you say

... and add re-enforcements to the inner rear mount since they were cracking.

Are those the inner trailing arm mounts? How much track time do you think he had on the car when you guys noticed cracking? 2 ,10 , 30+ track days???
