I have noticed some people talking about OTM (think it stands for On The Money) and they make a steering system for the Mi4CX and also pulleys.

Has anyone got any info on them - do they have a web site?

The twinpoint steering gives the same turn-in the mi3 CF steering thing did. basically the biggest difference is, that the ballstuds are closer together.

I'd say the only difference between a centerpoint and a twin-point steering feel-wise, as long as the ballstuds are the same distance apart, is that the twinpoint gives you a bit more feedback from the car, onpower only.

With the alloy pivot blocks you are able to lower the rollcenter which will give more overall traction and reduces tirewear. I run them 100% of times.

Hey guys,

I have updated my blog again :-)

I've gone the other way because with all the options like blocks and steering my car was heading towards nearly 80g over weight. My car has lost 55g now just by going back to the standard steering and plastic blocks. I really don't think i could get that back with titanium hinge pins or screws and i don't think i want to weaken it either which titanium will do.
Handling with out the alloy blocks is not as stable and grip is shifted forward but lap times at my local are the same. Maybe because less weight or maybe a livelier set-up works better at my local.
Steering wise i really liked the turn-in of the twin point steering and swore by it being quicker but go a little advice from a team driver about what he had found. Put the standard steering back in and did my quickest qualifier and quickest lap time, out of sixteen runs, with it straight away.

Pulleys are available on the schumacher site now and I've had a spy at the steering systems. They seem to be playing with narrowing the ball joint spacing of a simular system to the standard design but not sure who it is.

That doesn't seem possible. According to my scales, the difference should be about 15g for the blocks and 7-8g for the steering. You sure you didn't change anything else at the same time?

Also, are you running an LP or a CX?

I'm having to run with 35g ballast on my LP to get it up to 1350g.
Maybe I should add some of these alloy parts?

Running a CX. I made it 6-7 gram per corner. Thats pivot block and the longer screws that are needed for them. And about 15-20g for the steering. And yes just realized some of the wieght was due to a different motor. But even so it's a 40 gram saving minimum. I think a lot of my cars wieght problem is a GM90. Going to see how much a Hobbywing can shave off and might put the blocks back on.

Are you running the little shorty battery pack? I thought that was you who mentioned it.

now that I got rid of the shuie i really need to stop reading this thread.

you guys are just silly with the weight thing.

and not sure if the other guy ran one or not, but I ran a shorty lipo at Reedy and made the A with the car that was way over weight, and I mean way over. AND USING A DNA BODY

get over the weight thing, can't say it enough

let me just ask this,,, what is you hope to gain by having your car at 1380 vs 1425, or what is it that you think you will lose by having a heavy car.

With the alloy pivot blocks is the instructions 2mm front 1mm rear down spacers the same as the plastic ones?

Martin Hofer

1.0 front 2.0 rear! is the same as plastic

I use 1.8/1.5/2.5/2.5 front to back

I think you mis understood me. My car is weighing in at 1465 grams currently and im not going to waste my money on titanium screws and light weight bodies

Please discuss this steering change please. Always keen to hear others thoughts on this area.

I don't worry about the weight either my car as is now is over the legal weight but it's perfectly balanced on all 4 corners -

Yes I do run a Stumpy, and have pushed the weight to the rear (outdoor Asphault).
no duration problems with 13.5, and good punch.
