Hi guys. Greetings from Malta.

TEAM HD.

I suspect your slop problem is caused by a combination of factors. I have run MR4s for the last 3 or 4 years and have yet to find one without slop.

A couple of years ago Yoke produced hubs to take bearings of a bigger O/D. I presently run those on mine and it has partially solved the problem. Unfortunately they ever supplied cars with these hubs and bearings as standard. They have recently introduced some new front hubs - part number ZS-415S-1, but only for the small bearings, which means I can't use them. They give slightly different geometry.

A bigger bearing is always a better bet, so when you next need hubs and bearings I suggest you go for the big ones.

NEW WEB SITE.

Our club, the IRMCC has a new web site. Check it out on www.irmcc.com and let me know what you think guys.

Regards

Joe from sunny Malta.

Hi Guys,

I have seen new parts for the MR4TC such as 1 front bulkhead, 0 lower rear bulkhead, new rear hub carrier and 4 front hub carrier

in the original MR4TC,
how many kick-up degree has the front bulkhead ?
how many anti squat degree has the rear bulkhead ?

thanks

Hi guys. Greetings from Malta.

RALF.

As far as I know the standard front bulkhead has 1 degree perhaps 2 kick up at the most, whilst the standard rear bulkhead has no anti squat.

Yoke do make a front bulkhead with plenty of kick up. it is standard on the MX4 and possibly on the BC model too. I have one which I have never tried yet, though I know people that use it all the time on MR4s. I have my new ones on order.

Just come back from the track. I tried the car with the Sp top plate but found it too twitchy. I could get the odd quick lap but it was inconsistant so i have just reverted to my own top plate which gives even more flex. It's a 5 minute change job.

Regards

The standard front bulkhead and rear anti-squat blocks are 2 degrees. The new front bulkhead and rear anti-squat blocks will have 0 degrees and will only have 1 arm mounting hole wich is a mid roll center mount.

Thank you Guys,

Johnbull,
When you say you tried the SP top plate, is it the silver graphite one ?

Hi guys. Greetings from Malta.

RALF. I normally run an alloy shaft front to back instead of a top plate. It stops the chassis from folding up in the case of a frontalimpact but allows it to flex laterally. It is mounted with 2 rose joints.

I tried the standard SP top plate today but found that the car looses adhesion alot easier with it, so I have reverted to my alloy one.

Getting back to kick up and antisquat, I always thought the standard MR4 set up had hardly any of each. The arms always look absolutely flat. Interesting that the new ones should be zero degrees.

Looking at recent set up sheets for TC3s I see that they are all running them with no antisquat at the rear and no kick up at the front. Should be interesting.

Regards

Joe from sunny Malta.

Yes, I ran the graphite chassis on carpet. It was better. No tweaking and more consistant. Haven't run rubber tires on carpet this year, only foam. Other people running the stock class are still running my setup from last year though.

My SSG parts arrive in two days.

I am looking for a rolling Special car, if anybody has one for sale. Spare parts a plus.

Default Inner hinge pin mounts Help?

On the front and rear of the mr4tc you can change the mounting position of the inner hingepin.....when and why would one use the upper mount??

Does it simply lower the c/g of the car..or is really more of a roll center adjustment??

Generally I race on carpet with foam tires....any input.

Default ssg help

Can I use the lightweight silver worlds motor mount with ssg chassis and upper deck??

What is the difference between the blue sp motor mount and the silver alum motor mount from the worlds/hara edition??

The chassis kit is expensive enough and if I have to tak on another 30$ for motor mount that a $200 conversion kit...ouch!

The different holes for the inner hingepin is for altering the roll center of the car. Mo and myself ran a high roll center the last time I raced with foams on carpet and it ran pretty well. This is with the SSG chassis as well. One thing you guys are going to have to do with the new SSG chassis is drill a hole in the plastic right behind the front inner hinge pin and put a screw in it to hold the hinge pin in place. There's nothing to hold the hinge pin in place with the plate graphite chassis and trust me, the hinge pin WILL fall out if you don't do this

the silver mount will not fit because the holes are in different places.

you have to use the blue SP mount on teh ssg chassis.

the high roll center is useful for low grip tracks, I tend to run it on wooden floors where grip is less than minimal.
