As the downside of having all gears semi-straight cut is the annoying noise on long trips on the motorway. And would it be possible to mix with standard gears and semi-straight cut?
I do not think this will help much but my car did 30,000 miles on the std box at 330 bhp then as soon as I went to 420 on low boost but with loads of low down torque due to the twin scroll borg warner the box failed under very normal use...rattling third and second in under 100 miles.
