I have also made custom shafts for the vxr / 6 speed conversion into n/a instead of the europa shafts. As in joined with machined sleeve to join the astra to vx ones
That's brave! Seen it done many times... never seen it work... and Europa shafts are cheap enough.
They are not that cheap
and the conversion is is on a very strcit budget
Yep seen a lot over the years and seen a lot break managed to break a shaft once drag racing but looking back was not the best way to have joned them. The way I do them now works well and same way as the 600bhp atw renault 5 drag car and 4 years on they are going strong.
And of course the Europa item is there on the shelf in the future if required
