I have a 1st gen twin turbo carbon fiber driveshaft for sale. Has maybe 1000 at the most 1500 miles on it. Its the ACTP one which replaces the front portion of the driveshaft. It is a great performance booster and you do notice a difference. I'm going up to a 6-speed transmission and can't use it anymore. I'm looking around $800 for it. Normal cost is a little over $1000. If anyone is interested, please e-mail me at [email protected]. Thanks.
