Got my roll bar hoop the other day and fitted in the car. Works nice and sits just a tick above the targa bar.
Anyway I am going to put the forward diagonals from 4" below the curve of the hoop and have them end up 3-4 inches forward of the hand brake cut out. I am also going to penetrate the fire wall and tie in the rear shock towers to the hoop. is putting the Engman kit a good idea or would 16ga. scab plates under the bars at car connection points be enough. Remember lighter is better. Mainly concerned with stiffening the car for Autocross. at this point I wil never run Wheel to wheel racing in this car. (IMG:style_emoticons/default/driving.gif) |

No, Josh, you're right, but verticle deflection is what needs to be eliminated at both ends of the car. Reduced pitch bending of the chassis is what I am after.
It also helps with roll (twist) of the chassis. It stiffened things up quite nicely...shoulda done it years ago. The towers are a handy place to tie into. One other thing. The rear towers are NOT welded directly to the ends of the longs, but tied together with some sheet metal bits. I hear as rear spring rates rise, the towers can pop loose......that would suck. I saw some indications of that on the shitbox...minor, but not ignored. |
