My advice is to use 2.5 or 2.75" welded spacers and matching track-tuners. Here is how you can do so and keep your desired wheelbase. With 4" inner and 4" outer belts, you will have an 18" wide track just like your super-tracks. We know that "should" fit. If you go with a narrower inner crosser body (and belt) so you can use narrower spacers, you won't be able to run matching track tuners that small, and you lose belt-width and floatation on the inside. These would be huge drawbacks. Instead, you could continue to use 2.5" spacers, add 2.5" track tuners, and simply use a roughly 4" inner belt. This will give you adequate tub clearance. Then, instead of using the typical 4" outer belt, just use a 6" outer belt, making a 20" wide track that is set up properly and won't damage your tub. The best part is that the additional outer belt width past the crosser body will simply fold up if you need to squeeze it between trailer fenders or trees etc. The outer crosser body shouldn't extend past the current location of your supertracks. I'll attach a picture showing 2.75" spacers with 4" inner belts on one particular track. You can see how there is plenty of room to use a 1/4" smaller wheel spacer/tuner combo. I personally would not run that track with any less than a 2.5" spacer simply because of the ability to mount decent-width belts and track tuners. If you want the best performance. Luckily I think the wheelbases and clearances work out in your favor doing so! Hope that helps.
