Cuttin the roof off

[joel w]

2 allen bolts in front that point upwards and screw into the windshield post and 2 in the rear that point to the back and screw into the back part of the roof. with holding brackets that securly lock and hold it over the spare tire compartment without damaging the paint!! nice touch..

though i have a hardtop...i have a question about that...if you convert it wouldnt you have to stiffen up the all teh pillars? since the supra in targa top trim was a little heavier..due to a stiffened chassis to accomodate the targa when it is removed because they are designed to hold all the weight of the supra so roof doesnt..collapse when it rolls over...the hardtops were designed a little differently since there is no removable top

that could be, it was just a thought?

Drcusupra,

This is a Do-Luck (RXB) Center Support Bar. I would imagine it would take

most if not all of your flex worries away. Easy to install and fairly cheap.

This is what the manufacturer has to say;

Drastically stiffens up the weakest point in the unibody frame which helps to

eliminate body flex under extreme loading. Increases torsional as well as

overall structural rigidity. Note that the combination of a front, center and

rear bar works to create an approximate 100% increase in structural rigidity.

Only a rollcage helps further. Especially good for targa-equipped cars.

Cheers!,

As a professional bodyman, I wouldn't chance the removal of that hardtop. You will have major structural problems with that job, no matter what you buy aftermarket to install to correct. You'll need to take it to a professional to have it done. Talk about TWEAKing one. Wy to much body twist. An easier job would be to find a targa and make swaps to the new carcass.

hahha ya i figured i stir it up on that post. but what ive seen done,
They welded in cross braces and lateral braces inside to prevent any flexing or warping from occuring, then they chopped it and rewelded the new top in place, then and only then did they removed the temporary braces to ensure the body remained true to form, They made it look easy but talent and skill often does that.

i agree swapping the shell may be easier!! and what i saw done, was not performed on a supra!!!

I have a 1991 Hardtop. Its equipped with anti-sway bars (Front and rear) and i am waiting on my front and rear strut tower bars. For some reason im obssesed with stiffening the chassis i geuss I feel saferwhen im taking corners real fast lol. But that middle Support Bar is COOL!!!!! Can anybody tell me where to get it if its worth it for mine since its a hardtop? And also if they make a roll cage for the mkiii and how much it might run me? Thanks

ahh..moonraker thats wut i thought...so my theory was correct, the hardtop made the chassis mroe rigid...and thats how it was designed...if you make it a targa witout strengthening the chassis...you'll get a lot of flex.. as for a rollcage i got a custom monkeybars rollcage...it stiffens up the ride also.. so im not sure if u will still need a middle support bar
