hy guys,

I have a problem

I´m running a mi4cxl and in the rear i can move the sliders about 5 mm to left and right.

IN the front it´s not possible.

Can anybody tell me please if this is normal or what i can do to fix them?

Everything is build like from the manual..

I have a fair amount of slop, but nothing close to 5mm. I'm guessing you don't have the o-ring properly seated.

I would agree with gripgoat,,,you probably don't have the rear sliders seated on the o-ring properly...

Okay guys,

Had my first race with the 4CXL and found that I had massive under-steer off power. On power steering was good mid-corner and the rear would step out slightly on heavy acceleration out of the corner.

I am thinking about trying the following things one at a time to see if it will help.

1. Move battery to more centered position, it is currently forward.
2. Drop from pink to silver springs in the front.
3. Add .5 degree of toe-out to the front.
4. Lay the rear shocks in a position or two.

Any thoughts on whether or not this will help? Any other things I should be trying?

I am also noticing that it is light on the right side so may move to a full pack rather than the shorty as the car is light overall.

Thanks

Interesting... That's a pretty big left/right imbalance. I'd fix that first.

Your weight balance is also relatively far back, about like mine with battery in the rear. So I'm not sure moving it back is the best first move. If it's easy to try, though, go for it.

I'm not sure what to think about the setup, because I've never run without swaybars. Have you tried with them on? If you haven't, I'd try that next.

Silver front springs are worth trying, but I'd expect that to give you less turn-in response, with more mid-corner steering. If I remember correctly, my car was pushy but fast with pink / silver on asphalt. I'd definitely try the sways first.

.5 toe out per side probably won't make a huge difference. I'd save that for later.

I'd also try a bit more droop to see if it gets you more overall grip. Try 5/5 or even 5/4.5 to see if letting the rear roll more helps anything. Theory says that more rear droop lets more weight transfer to the front on corner entry. I found it would make the car push mid corner, though. also, on asphalt I find that more overall droop lets the front end dig in and bite harder. that's bad on carpet, but lets the car take a nice set on asphalt. Are you running only -1 camber because of tire wear? If so, more overall droop should help that. in any case, if you do sways and mess with droop, you'll need to experiment with camber again. my baseline is always -1.5*.

Mike, thanks for the info! I will start with the L/R balance for sure. Reading your post made me think about it and the main corner I am having issues with is a left hander. Adding some weight to the right side might get me some more grip.

On the rear weight bias, I am running a pretty small spur which is locating the motor almost as far back as possible. Perhaps a larger spur may have a big impact but I will save that for later.

I have a set of the swaybars but have not given them a try yet. I was under the impression that they would lessen the weight transfer and the traction along with it. It has been a long time since I ran touring car so I may be going in the totally wrong direction here. In any case, I can fit them up this weekend and see how they affect things.

I am running -1 of camber purely as a starting point tho I did notice very uniform tire wear with it. I can certainly live with some tire wear if it helps this push so will tinker there as well. Front only or do you recommend the rear as well?

What is the recommended setup with this car for bumpy medium grip asphalt?

I ran on asphalt, my set up is 35~40WT oil in shocks. 1.5degree camber all around, front toe 1, rear toe 3, stock tract width, flex upper deck, droop 6 front 4.5 rear. ride height 5 front 5.5 rear. everything else is stock I think, not sure if that works for you

Attached is my final high grip carpet setup. Saving it here before I completely rearrange the car for asphalt.

The main limitation with this setup was getting good steering and corner speed while avoiding traction roll.

Still working on it. I ran my carpet setup (just posted) with the exception of Ride Red springs all around, droop set to about 4.5f/5r, full rear battery, with old Team Powers 32's and 36s, running a boosted 10.5. The car did not want to turn. It wasn't too bad when the tires were fresh out of the warmers, but it got worse over the run. I lunched my rear diff in the main, so it wasn't diffing at all.

After playing with the car on the bench a bit, and I think the camber link setup is just totally wrong for asphalt, especially in combination with the springs. I think the rear is gripping OK because it doesn't roll and lose much camber, but the front rolls more and loses a lot of camber and grip.

I'm pretty sure the 3 groove top links plates are still the preferred choice for ashpalt, gripgoat.

Are replacement bones for the True CV front driveshafts available? I can't find them listed on Schumacher's site.
