Carbon Fiber Roof!!

Green7mgte · 08-11-2010, 09:19 PM

ian is absoluty correct.. much more vibration in the cockpit with the top off and the car is more prone to "wobble." thats what happends when non roadster designed cars, chop their tops off.. your left with a feeling of something in the support is missing. cause it is. the car is less ridged. but its really not a big deal. I dont have the bars across my targa. but i don't drive above 90 either.. 80 if im paying attention.

YEAH!!!! Rice ruleZ!!!

Ugh... anyway, the roof doesn't take 60% of the vehicle's torsional load... I don't buy that for a second. It does take a significant amount though and to offset that additional bracing must be added elsewhere... there's a reason the targa models weight ~150lbs more than hard top models.

The floor pan has a lot of extra material.

Like I said before.. I ain't going with the weather man this time. He said it would rain yesterday and look!! 90o clear skys! I think I will carry the umbrella (front and rear sway bars). I WILL NEVER WEAR THE BOOTS (especially since they are made for walking)!

WTF are you talking about? Not speculation. Just a fact. Targa's have a lot of wiggle to them and close to 150 extra pounds of reinforcement to make up for it....

... weatherman? WTF is wrong with you.

Who said I wouldn't have it reinforced with some heavy materials? I get that.. Whatever the case is. The sway bars will help.. Still sunny and not a cloud in sight..

I don't care if the targa is 150lbs more with top off the supra looks bad ass

I bet that's nice in Baltimore..! Wish I still lived there with my Supra!

I purchased my Supra in January of 89. Spent three months finding a 5 speed hard top turbo. No regrets.

I'm not saying there's anything wrong with owning a "sport roof" MKIII... Just saying that they're soggy enough and if you're going to drop some coin on another roof you'd do well to get one that's reinforced... sheesh.

PS: Sway bars have NOTHING to do with twist.

What sort of reinforcing can I do to my Supra? Been feeling like a real dolt lately of course the roof is part of the structure and the car is even more soft without it. First blowing out my rack in pinion steering and power steering pump, then all of the minor leaks after fixing the main ones. One of these is in the rear of the engine.

I love driving my Supra

It is just that it needs some more attention and a paint job. The clear coat is peeling off of it.
So what can I do to stiffen up the suspension? I love driving with the top off.
