Default help

Hi Guys I don't know if you can help me but .... i run a 415msx i am running a comp this weekend and I've been told that the surface is carpet but track temp is about 7 degree C. I am runing rubber hpi vinage tyres which is the class, so I need to take steering away and add traction to the rear. I know I am asking alot but has any one a setup I can start with. I was going to put a diff in the front and I was thinking of putting a JUNN rear end to add traction, am I going in the right direction. HELPPPPP

TJ- Although I have no experience of the Tyre, if the track and tyre are both low grip, I would possibly be looking at softer oils and springs to help the car with the steering.

Low grip and harder springs = drifting, or spinning out

A diff will make the car easier to drive, which if you're not used to lower grip levels, should help you out

Unless the track is very high speed and flowing, where a one way could be beneficial, but you'll have less brakes. Never used a spool on low grip tracks to say anything about that.

3 degrees rear toe should get the back end feeling pretty stable too.

I ran my 415 msx for the first time last night with the short arm suspension, alll i can say is wow

we ran a new layout with some tight hairpins and i was dreading it as i always suffered with understeer, but a few changes and the new short arms, it has never felt that good.

I run 540, so i am not up there with the top class, but the car was the best i have ever had.

CARPET SET UP QUESTION:

We race on ashpalt all the time but there is a series round here in Australia that is on carpet, never ran on that before.

What are some tips to run the 415 msx on carpet.

This is 540 class and will be on foams:

Any tip and any setup would be great

Thanks


chris

Chris, if the track is rather flowing, you may want to try a one way, to carry as much corner speed as possible.

However, using a one way you will have brakes (I doubt you will need them much with the speed of a 540 though )

Make the car as light as possible too (or as close as you can to the weight limit if there is one).

If the track is more technical, you might want to look at increasing rear toe to 3degrees to help the back of the car feel more stable on cornering.

Ride height 4.5 or 5mm and full rebound on the shocks would be a good starting point. Depending on the shore compound of the tyres and the grip levels, you will probably be using stiffer springs than the kit ones too...

Since I'm having a hard time finding the alloy knuckles for the 415 in stock anywhere, will it be difficult for me to run the 416 knuckles? I'm already running the short rev suspension.

The 415 knuckle uses 950(9x5) bearings and the 416 knuckle uses 1050(10x5) bearings and the 416 knuckle uses a slightly longer wheel axle(TB-03).

Which also means you may need a slightly shorter driveshaft. But this depends on the blocks your using...

I did the complete short arm suspension conversion when I still had my MSX, the 415 kit drive shafts(46mm) work perfectly.

That should be fine to start with, you've got 0.5 degree toe out at the front and 3 degrees toe in at the rear.

Here's a link that will help with the suspension blocks

In the front it's called "sweep" since toe is actually controlled by the steering tie-rods...
