Hey guys what brakes are most of you using? I am on my 5th Losi 8ight and it seems like every one I have problems with the stock brakes. I don't know if my pad to caliper clearance isn't right or what. But I always try to set it to where at idle there is NO drag at all on the brakes. But even like that my pads seem to be dragging and even when I apply the brakes they don't stop the buggy like they should. Seems like no braking power even with a high torque servo. I even tried the trinity spring things and it didn't seem to change anything. Actually it seemed to make it worse. I have a new set of Advantage Drilled brake discs here but when I went to put them on they fit REAL loose over the diff outdrives. They had tons of slop so I put the stockers back on for now.

Just looking for opinions that may help me......

I use the ofna ( ofn 40044)brake springs and leave very little gap between the calipers.

If you have to much gap they will bind when you accelerate and decelerate or when you tilt the car back or forward.

I think what you said is what's happening to me. I'm paranoid about having the brakes too tight so I always back off the calipers. I just took the center diff out of the buggy and took a look. It looks like I had too much of a gap between the discs and calipers.......

Make sure there is .5mm clearance between pads and rotors. The newer HD brake disc from Losi work well also. I just ran them at the Nitro Challenge and worked awesome.

It was only muddy on intermediate buggy qualifying and the first few truck mains. I had the upgraded discs on my truggy and they worked really good.

Lars- What's up with the whole Blue compound? I thought it was supposed to be super special dialed for 1/8 outdoors, but then these new tires are only available in red and silver...

I was fortunate that the track wasn't that muddy during my run. I felt bad watching a lot of racers standing in line to the hose to rinse off thier cars.

I know all the GRP tires are coming in Blue compound, and XBT's and Step Pins are too. They just might not have the Eclipse's done in blue yet, i'm not sure.

This probably has already been brought up before. Is blue between red and silver? I guess I have never really known!

Good job at the Nitro Challenge, Lars! If you are coming over to MN again this summer bring your stuff again! It was a blast racing you!

someone posted this on sgrid yesterday, i copied/pasted it.



Silver: An excellent all-around tire compound. Silver compound tires
work best in situations where the Red compound tires provide too much
grip. You will commonly use Silver front tires to help desensitize the
front end and take steering away.

Red: Red compound tires are widely used on hard-packed outdoor
racetracks. Losis red compound tires provide exceptional bite and
tread life. The Red compound is softer than the Silver compound, yet
slightly firmer than White.

White: Tires molded from the White compound rubber will have increased
grip when compared to the same tire in a Red or Silver compound. If
you are searching for more grip on one or both ends of your vehicle, a
White compound tire will yield more traction.

Pink: Pink compound tires are the hot ticket when racing on tacky
indoor tracks that have a lot of traction. If youre racing on a track
that calls for a low-profile pin, give the pink compound a try.

Blue: Designed to handle the rigors of 1/8-scale nitro racing, blue
compound tires provide a competitive advantage to nitro fanatics.

I talked to Adam about the blues. In Losi tires they would still be a harder tire than reds. In the GRP tire they would be softer and maybe closer to a red.

Thanks dude, that is definitely a race that everyone should do sometime. I'm going to try to make it up for another series race this year, just gotta figure out when it works. To me, the Blue's work similar to Silver's, with a lot more longevity. I think in certain situations where a blue groove starts showing up, where a red tire would be fastest, a silver would work well - a blue would work similarly to silvers with a longer tread life. Obviously it won't react the same in some areas, but as far as tread life goes, a Blue should outlast everything. I know that the blue XTT's that come with the 8-T worked great at my local track Rat Raceway, which can be abrasive on tires; they far and away outlasted Gators and CrimeFighters.

Just an update on the brake situation:

I took the center diff out and measured the clearance I had and it was right at 3 times what is required. It was 1.45mm instead of the .5mm it needed to be. I put it at .5mm and put a new set of Advantage brakes on and fine tuned the linkage and now it's perfect. It doesn't drag at all at idle or WOT and the brakes will lock up if I need them to. I set the brake bias about 70r/30f so I can let the brakes help the buggy rotate.


Back to the tire talk:

The stock xtt truggy tires worked well for me too. They have tons of traction and a long life too. I'm hoping the xbt buggy tires that came on my race roller buggy work just as well.

Mine did the same thing, they are not all the way in. I had to dremel part of the insert surface. I think the inside. Take it apart and have a look.

Anyone got a part # to make the front rod ends captured????
