Yep. Removing rear traction, or adding front traction, will both provide more perceived front traction. My way nets more traction, your way nets less. Which you use would depend on how close to traction rolling you are.

I am actually -2mm inside and inside 2 hole down on mine. But we race on a very edgy clay track with frequent traction rolls.

Ah, I mis-read an thought you were referring to the rear. My mistake.

I usually keep 2mm washer on the front inner camber link as standard (so I don't usually go up from there and don't prefer to lengthen the front link) and go down as grip increases, and likewise on the rear to keep a roll balance.

Can you clarify what you mean by mid corner. Are you decelerating in just before the apex, accelerating out just past the apex, or really just stuck in the middle of the corner forced to go slow because the car didn't make the corner and leveled out.

You will find that, with team setups, the harder you drive into the corner, the more the car will turn. Have you tried absolutely blasting the corner

Asked previously-

Does anyone have a chart of the smallest and largest pinions that fit onto the Spurs. Just trying to save myself the legwork.

If so I can do a FDR chart in excel/pdf for everyone to save and/or print out

75 spur min pinion is 25

This is assuming a standard motor plate

Back of the manual has gearing suggestions, if that's what you're after. There's no reason to use anything but a 69/72 spur for 17.5, and a 78 for mod.

I race on a huge 1/8th track on some weekends then small 10th tracks otherwise. Very different.Randy Pike from Tekin recommended I try around 7.9 fdr for the small track. I got the RPM motor. I worked it out for a 72 spur and then the pinion wouldn't reach. So was hoping someone had a table somewhere. To save me the annoyance of changing pinions and Spurs not knowing if they'll fit.
I suppose if I stick to the Spurs you recommend I'll work it out pretty quickly. Thanks.

The track im talking about is super high bite (when they groom it correctly) LRH where we run slicks. I got it pretty much figured out by removing 2mm of inner camber link ball stud washers. It did give me more mid-corner on power steering, Not sure why. I also noticed a build error, I was sent the +4mm C arm mount. Didnt know there was a newer arm mount out, it's been a while since I ran AE. Suffice to say my rear end was too wide running that plate and 7mm hexes. Got the standard C plate and gained all kinds of steering everywhere since the track width of the rear of the car is now correct. I could use that LCG gearbox.

It was a build error, was sent the +4mm C plate and used it with the 7mm rear hubs. Car was a wide boy. replaced it with the right c mount, and its fine now.

Was there last night. Yokomo, and B5M both were really good after some changes. Getting close to high 15's in stock buggy. Both buggies are pretty much neck and neck, but I give the overall steering feel to the Yokomo.

Petit rc has an fdr chart under their b5 setup page you can print. It doesn't specifically say if they fit or not but at least the math is done.
