Re: those with shifter issues, enter now!
i can't tell you if you should buy parts or not, but this is my experience with it:
i tried the original prototype out on my car with no other shifter products. i found the shifting accuracy increased dramatically. i was able to repeatably powershift (gas pedal matted) 2-3 an astounding 100% of the time, where before i was at about 25% success from a highway on-ramp (this became part of my test loop) and about 60% success on the drag strip. i had issues finding the proper gear during on track heel-toe downshifting about 25% of the time. that is also gone.
the stock shifter was working very well, but i missed the tight and crisp shifting the steeda tri-ax shifter gave me. so, i put the steeda back on and its just so much nicer of an experience. it just feels more direct with a well-built aftermarket shifter.
so, in my experience, a good shifter with this magical new product of mine is a match made in heaven. i would actually like to do my own shifter down the road and do it as a complete package, as i still think there is room for improvement over every shifter on the market today, but thats a major undertaking to do it the way i want it. it will be a while.
i would stay away from the barton bracket or any other manfacturer's variation of it. my doodad does away with these brackets, so you will just end up putting it on ebay. the whiteline insert is a matter of preference. it will not help or hurt shifting with the blowfish solution. don't under any circumstance get the CHE torque limiter. thats just a huge strain on the bellhousing. i think that covers all the "shifting aids".
if your clutch pedal sticks to the floor, that is a different issue. go ahead and find anything you can to fix it. you will want your clutch working well once your shifter starts working right!
