hi
vette2vette sent some pics, pretty easy once you see a picture. install took about 3 hrs but I went slow. you did have to drill a 7/16 hole which I wasn't crazy about . I had some clearance issues in the driver side front bracket, it was hitting the brake lines. Had to move them a b it and the driver back bracket hit the emergency cable. overall a nice fit. I will let you know if it was worth it.
thanks
todd

Interested to see how you like it and if it made a difference. Most people that shell out $$ for something will always say its worth it. You seem pretty objective about it.

Wow, I never had to drill any holes on my install. Curious where the drilled holes are.
But I did have the interference with the ebrake cable.

Finally got around to taking my corvette out after installing the c4 no flex bars. It definitely had a lot less shake when the top was off.I still think it feels more solid with the top on. I may have to do some adjustments to bars to get all of the shake out. I am going to mess around with it next weekend. Will keep you posted.

Are you talking about more tightening of the bars?

I'm wondering if you can actually affect the A-B pillar spacing with these bars? Meaning increase/decrease the amount of space between the pillars.

yes , it doesn't tell you in the instructions how tight to make the bars. I did then pretty tight with only 2 or 3 threads left to tighten on each side.

I have 2 sets, the latest set has a extra hole in the rear most attachment.
I guess it's a improvement from the first design.
In regards to the adjustment, I tightened the bar until I had minimal deflection of the chassis.
I took the top off, used a jacking point that would induce the most flex in the chassis. After final adjustment I had 1 mm of deflection

In case you guys in Tech are curious, I posted a blurb from V2V on the theory behind the system. I'm thinking of buying one myself.

The comments from Jason at V2V are in a General Forum thread...
