I'm located in adelaide; Australia.

My local track is at hobby habit, where there is medium to high grip; and sometimes there is no grip at all due to insufficient cleaning. This is a good, fast passed track, but due to the track outline being wood, it's not very car friendly!

Thanks
Bill

He was racing 17.5 boosted last season but moving to mod this year. If you know Steve Young he also races with us and at hobby habit if you need any help. The car is pretty good out of the box, have'nt been to HH for a long time but if you come Sunday I will show you what we have done to our car.

Also, how do I tell if I have DJ shafts or not? My previously used Schumacher mi3.5 I bought second hand with a crap load of parts to come with. If these are double joint, how do I tell? And will they fit in the BD7?

A DCJ has 2 joints, a UJ/CV has one, it's easy to spot.

Each joint is going through half of the angle a single joint would be going through. It's supposed to prevent spool chatter, where the front wheels vibrate quite badly as more steering lock is applied.
I've never used them, was going to be testing some tonight but unfortunately we won't be running tonight.

I had and to an extent still have the same problem as you with needing more steering when running modified. Increase your droop 1mm front and rear and raise your rear shock position. This will help some. If you need more, add 1mm to steering rack ball ends.

If you find out anything else, let me know as Im curious to try other things as well.

17.5 no timing: 4.0
13.5 no timing: 4.5

I hardly change my gear ratio from the above at the local track.
