Nice one millzy.
Still yet to give mine a proper run ... its been a donor car for others.:)

What doe's flipping the Ackerman bar do

It gives more steering , and by lowering it you get more bump steer

What do you use for crush tubes in the front hubs. I have used 5x7x? spacers in the rear hubs but there is so little space in the fronts with the "down pivot" close to the axle.

Center of old bearings, filed down to fit

Cheers - hadn't thought of that - will try that tonight.

it was a tip from one of the other drivers, and a good one too.

MOre steering? Don't the steering hubs touch the caster hubs?

pics please if you can

Yes they do, but on full lock you sterring should not touch the caster block bump stops. you can allways sand down the caster blocks or steering arms if on full lock you fell your still not hitting 100% of the servo throw

its more to do with the angle the wheels sit on that the lock you get.

pic will be next week , racing this weekend

Thanks Millzy,

I will try a simillar setup tonight. The car was okay but wasn't good in tight turns. The shorter wheelbase might help.

Stupid questions :blush:

Axle set to low.....what do you mean??

Ackerman bar flipped.....where is this??

Sorry for the above questions :blush:

ackerman bar item no. 125000423
I don' t know how to lower it tho

Hi Guys, Ackerman flipped: This is at the front behind the bulkhead , its the bar that your steering turnbuckles pick up form to your starring arms, its lowed by placing shimz between the bar and the servo saver pick ups.

Axel low: the axel that the front wheel sits on, the steering arm is skimmed so that when sat in the caster block it’s at its lowest setting, its then shimed to stay low

what toe in are you runnig? i find the 4 deg is good if there is a lot of polish, but you will suffer a little on any carpet 180 bends, try going back to 3deg toe in on the rear

Im sstill playing with the rear camber link pick up right now- will report back on that

how many shims you put in there? and longer screws as well might me needed

axel low so the shims are put at the top. that can't be a big difference right?

What setup equiptment are you using?

Just two wheelbase shims on both ( i belive the kit has one shim on the axel height- you will need to skim the bottom of the sterring arm to lower the axel) the bar and the axel , and no you don’t need longer screws.

lowering the axel will keep the front wheel closer/or pushed to the ground when the car is leaning over in a bend, but it also lowers the bumps steer, lowering the Ackerman bar resets the bump steer back to kit.

Hope this helps
