FWIW I'm assuming you know this but in case you don't, you can tighten the belts, there just isn't a center post style tensioner...you have to rotate the diff/spool to tighten them. I'm running 13.5 and opted for the low friction white belts. After a few packs, I had to tighten the the front belt 1 notch and it was plenty tight. After tightening, no slippage issues whatsoever.

Personally I run the white belts with the rear diff 1 notch off of center so that it's looser. This seems to be a good setting to keep the rear belt loose without skipping when using the white ones. I'm not sure how loose you can run the rear belt on other cars, but to me this seems good on the T4.

Which belt are you using (white or black)? What notch do you have the diff eccentric in?

Just doesn't sound right that the rear belt needs to be tight. It should have some give in it and still drive properly.

Well I admit it's been a long time since I've used black belts, so I'm not certain how they compare to the white belts as far as tension goes. I'd imagine they'd be pretty similar so you could probably get away with running it 1 notch looser, though I also imagine you've probably tried that already.

The one thing I found in the black vs white belts is the black belts tend to pick up a lot more junk vs the white belts... Which will eventually tighten things up after they work their way into the pullies.

I'm running white belts. I installed the black belts first for reference, then the whites. Whites feel a little looser than the blacks with the diffs in the same positions. I had some slippage with the front white belt after a couple packs, so tightened it one notch from center. Rear belt is in the center (down) position still. No issues here so far. I'm running 13.5 blinky at my track, so can probably run my belts a little looser than the mod guys. Racing this weekend, so going to try running the rear a notch looser if I can. I'll report back if any issues.

Yep, I agree the whites definitely do have a break-in period & can be tightened after a few runs unless you started out in the eventual sweet spot.
