I was told by a local pro to shove stock rear tire foam into the 4w front tire/rim setup and only trim the inside so it doesn't interfere with the bead when gluing. Trimming the outside edges lets the tire become too rounded, less contact with the ground. Full foam keeps the tread stretched out flatter. Dialed setup for me.
Bomb 1 inserts were said to be too firm for the front.
Anyhow that's the way I heard it.

Ditto! Proline foams are awful. They degrade very quickly. Get you some Panther or Trinity foams. How can Proline make such great tires but dreadful foams!

I opened up a set of step-pins I had been using for a while that were pretty flat...pulled out the insert and it looked like a shaped on-road insert. Pro-line foams do suck for sure.

I run a full rear foam with the corners trimmed a bit, outside edge and at the bead.

Run trinity grey for smoother surface, high bite.... stock for a bumpier track. If you don't like proline foam, use a stock rear losi foam. you should have a few extras around if you ever run aftermarket foams.

I run a lot of pink tapers with grey foam... indoors.. so I can always find a pair of stock foams to use for front 4wd and even 2wd buggy when you want a firm setup. We run a full rear in front 2wd tires when running slicks.... trimmed but full width.

Aren't the bomb ones way to firm to run in a hardpacked indoor track? I had a set with them and the tires were sliding all over they were so firm.

Another way to think of foams is that they are essentially the tire's air pressure. You want a softer tire for low grip and bumpy conditions so the tire can have a bigger contact patch and better bump absorbtion. A High bite surface needs a harder foam to support the tire under the higher cornering loads. Too soft a foam and the tire collapses under load.

Do not cut. The width reduces ballooning and and stiffens the sidewall. I have run them both ways and adamantly believe that trimming the width reduces overall performance.
