i asked 813 a while ago about this, the frame really doesnt need much stiffening, but could probably benfit from it if u track ur car often (like myself)

however the point when i lol'd and walked away is when he said itd cost about 8k for the process 2 b completed.

 

Yea if those people didn't fake on my Targa then we'd all be running around with Targa's as they were going to sell the kit for like 5Grand.

 

I had a 1984 300ZX Turbo with the T-Tops and absolutely loved it. I know, it's not targa, but it's close. The only thing that proved to be a royal pain in the butt was when the seals began leaking...not cool. I like the targa look, but I'm not paying 8k for it (that's a whole TT setup)!!!!
