Keeping the thread alive.

I just got back from vacation so my son and I will be heading back to SRS this week to race our 2wd stuff and get some more 4wd practice time.

Still waiting on the B4 shaft. Hopefully, it will be here soon.

I have tested the Tamiya slipper running B4 gear and pads and works perfect, I had a friend redrill the hole and all good.

I have heard a lot of people complain about the back end bouncing around which I was able to replicate in stock form as the supplied springs are rubbish. I have an old set of Kyosho gold shocks running softer springs with heavy oil which I put on and it fixed the problem straight away. Maybe kit shocks will work but they definately need a lot better springs on them.

the kit springs are a tad hard, but it it more the piston and oil in the shock that causes the 'bouncing', you need to go to the small piston to increase pack and create some damping to the unit.

I got my Tamiya heatsinks and slipper last week, but as yet I havent had a chance to try it out. Just need to find the ZX5 bits now and see how well it fits together.

I have a very busy 6 weeks period with touring cars atm so it may be a while before I get to run the DI again

I actually discovered a neat little trick when re-building the back of the car....

We all know that there isn't a lot of room for the motor to move, and whilst it's possible to elongate the motor holes to get it move forward a bit more, it also entails grinding away some of those strengthening ribs on the chassis.

Also, I've also noticed that with the curve of the chassis under the motor - the more you move the motor forward, the more it begins to rub heavily on the chassis at the bottom.

Anyway, what I did was to raise the rear gearbox by 1mm, just by putting 1mm shims where the screws under the rear gearbox go, and under the front part of the gearbox that bolts to the upper part of the chassis.

It doesn't effect the driveshaft angle very much (i made sure I tested that), but it does give enough clearance for the motor to slide more freely

Woohoo!! I got my B4 slipper shaft from England today and my Tamiys slipper kit (I like to hedge my bets) from Japan. The Tamiya unit will be a backup, just in case.

After a quick trip to the LHS for AE slipper parts, I installed the B4 shaft tonight. It went together very well. You don't use the brass bushing on the output shaft and you do not use the Associated slipper spring nut. It uses a 3mm nut.

A very nice piece it is. I'll be out at SRS Wednesday to test it out.

I am wanting to upgrade the front driveshafts to universals, other than the genuine Tamyia DF-02 shafts what other makes will fit e.g. Square, Tobee or 3racing. I have seen some decently priced square racing and wanting to know if they fit

Tobee do some.

The B4 slipper shaft was designed to work with the car, so no point having a 4-40locknut on there, so I opted to have RW machine a 3mm thread.

I agree with that. Why have 1 standard nut to keep track of in all the metrics. Makes sense.
