to me a 4 ponit is useless because it doesnt strengthen the integrit yof the car. flame suit is on
Agreed
Through the floor subframes is what really does the trick to tie the whole car together. But its all dependen on the rest of the cage.
A 4 point with through the floor subframes tieing it all together will help.....but not as much as bring it up to a 6 point roll bar where you have 2 bars going to the front of the car helping tie everything together.
4 point, 6 point, 8 point etc. back seat access is already going to be a problem. And for the door bars you can think about swing out arms they are legal up to certian speeds/times.
