For all 996 cars. With the construction of the 996 firewall/strut tower, a strut tower brace is NOT really needed according to most experts. However, I would swear that I noticed improved steering response on my 996TT.....Current retail on this unit is $499. Will sell this unit from my lease returned TT for $250 plus shipping. PayPal OK. Please email me at: grecomfs@surgical.net if interested.
