Well my Shumachers turnbuckles (which I had on hand, same size anyway) are 2.5gr each precisely. Titanium is just under 2x lighter than steel so over 6 turnbuckles you're going to win about 7.5gr at the best.
One misconception is that titanium is tougher than steel... it is true but pretty rare : the toughest titanium alloy is tougher than poor/cheap steel alloy steel and that's about it. Titanium can only dream of reaching high tensile steel strength.
I was surprised to see that associated gave us 12.9 screw quality which gives us a strength of 1200Mpa (ultimate) at 90% (yield). Extremely High quality titanium aerospace grade alloy won't go much further than 900Mpa (ultimate). So going for Ti screws on the B5 is for the weight/corrosion resistance not the strength.

Anyway I just received the B5 gear diff and it is by a long shot the smoothest I ever had ! Even compared with my 22 and Kf who've been run and breaked in for a long time ! Very impressed . There's very little break in to do from new.

I think they have discontinued the RSX one10 Response and replaced it with the BSX2 one10 Response servo. When I went to buy another RSX one10 this is what I was told/sold anyway. Essentially the same servo but with a brushless motor; a little more torque and .01s slower than the RSX.

Yeah, the Lunsford Ti turnbuckles are about 0.6g each lighter than the standard steel RB6 turnbuckles, so 3.6g total saving. That's for the Punisher series. The 3.5mm heavy duty ones would be about as heavy as the standard steel ones.

Hey Guys,

Just wanted to share Jeremy Harris' ROAR Nationals winning setup. It looks pretty standard until you get to the shock package. I ran it on my car in mod and it got better and better as the track go bumpier.

check it out: http://dialedsetups.com/sheets/assoc...onals-1496.pdf

Has anyone done the mod to the caster block bushings and replaced them with bearings? Curious if it makes any noticeable improvements.

way to soft for me. 1.9 in the rear and 1.7s up front...pass. The rest of the setup look good. If i get pucks, I also plan to use the brass front suspension holder to keep weight in the back of the car.

They were the kit molded pistons that he did in fact drill out.

lol, that was not the point Bob. It wont for for me. I tried 1.7 with high weight oils and the car was a slapomatic. A car slapping is like nails on a chalk board to me. I sold all of my cars that slapped lol. He might have gone that light for the bumps/pot holes in the track. The tracks around here are not that rough. No need to for those huge holes. The rest of his setup looks fine. Again, the big holes were probably for that blown out track.

yeah, that is what I figured. I would be curious to see if he tried the 1.4x3 tapers. I would think they might be more ideal for a rutted up track.

I'm sure that it was totally dictated by the track conditions. After talking with my friends who were there, I wouldn't put any stock into any setups that you see coming out of this race that look off the wall. This race was 99.9% tires and staying on top of the track conditions.

Mike said he ran his exact setup that he runs back home (which you guys all saw was very close to stock) only with a shorty pack. Said his cars were perfect. He had B main pace all week and kept making that one mistake or getting caught in traffic that one time. At that level, one mistake is 10-20 spots, which tossed him in the D.

Alex didn't say anything about his setups, but knowing him, I'm sure it was a similar situation. He ended up in the C, but similar situation as Mike. Cars were on pace, had the lap times and consistency, but would have that one lap where they piped it or got into traffic and ruined their run.

P.S. After hearing from these guys, no way in hell I'm going to FL in the summer
