They may claim will not work with standard trans due to the way the stock clutch linkage works- shares the
shaft with the brake petal and their bracket would be
in the way for the stock clutch linkage. As stated if your setup is ok then it should not effect the brake.
If you have as much clearance to the exhaust as stated
I find it hard to believe it is causing your problem but be sure to check it with the weight of the driver
in place
