1. Custom or Euro gears will prolly be expensive as heck
2. Quaife sells a gearset, check NFS UK, don't know about specs.
3. Even if you get a custom burnt chip to raise the rev limiter, you'll still have to shift to 4th. I do.
My limiter was set @ 7400rpm, and I would hit that about 30-40 before the line.
My 93.8mph trap speed proves that.
