so what would be the best tires for blue grooved clay for the b4.1. I was using doule dees but was thinking around red bk bars would work better...any suggestions?

Indoors Or Outdoors .?

Indoors Blue Groove Pink Bk Bars in the rear/Gold Barcodes Rear/pink Tapers Front/Gold Barcodes Front .

Outdoors Red Bk Bars Rear /Silver Tapers Front ...

Anybody used trinity bomb one foams in the rear, either# 1511 or #1521? I've seen that people like them, but wondering how fast they breakdown..stock foams are terrible and seem to break down fairly quick, except when using them in the fronts. I've tried jconcepts closed cells and they're a little stiff, and pro lines seem to be sold out in most places..just looking for an alternative, and these look good as long as they don't breakdown too easily.

yea and yea.

what rear buggy tires for my b4.1 would work well on a hard hard packed topsoil dirt track with a tiny bit of clay on the surface, proline holeshots in m3 compound work well just inconsistant with track condition, i orderd some green double dees....??

I use the 1521 for the fronts cut down and 1511 in the rear. Really good combo and yes they do last a lot longer then most of the other foams. I have yet to see them get to soft on any of mine. Im at the track no less then one day a week so there are a lot of laps on them.

Do you cut the fronts to 3/4 or the width of the tire/wheel?

I have tried both at my track and I liked the Dbl Dee over the holeshot all day long. If its a dust free so to speak I'd look at a v2 bar code.

i agree with dust doube dees...without bk bars red

My method is lay the tire and insert next to each other on the bench. Then take my knife and lay it across the tire and poke the insert. Then cut all the way around it. Makes for a nice fit. I'm partial to the jconcepts tires and this way its not over stuffed or flat feeling when done either.

Thanks for the info. Been running jc closed cells so curious to see how the bomb 1s perform.

I wanted to try them indoors but never got to. Maybe next winter.lol. to stiff for these outdoor tracks around here for me.
Your welcome. Keep us posted.

i tryed pink bk bars and it was bad lol. and yea there is a small bit of sand and marbles when you get some cars on it in the morning, when sun goes down and track stays wet i find hole shots worn down work great. I might try some flipouts since taperpins did work when the track was wet but tiny loose, the flipouts should possibly work, but ill see how these green dds work,ill get back to you guys.

I've never had DD's or flip outs work on anything other than a loomy track, even on dusty track a holeshot style tire works better for me..IMO

Hey guys I have a b4 what do I need to covert it to a t4? Or am I better off selling the b4 to get a t4
