The M coupe bar is 19mm vs the M roadster bar which is 18mm. I have the coupe bar in my ti and it made a noticeable difference in the handling of the car. A relatively cheap and must have upgrade for anyone upgrading a ti's suspension.
All I changed were the brackets, bushings and bar. All stock M coupe pieces. You could go with urethane but I don't feel it could be a huge improvement. |
