I am curious what your thoughts may be on the following:
My B5M is almost perfect. We run on a medium to lower traction surface indoors. The B5M has been fantastic taking the win last weekend. I would like to obtain just a little more rear grip or forward bite upon corner exit. The car tends to step out a little bit right when you pick up the throttle on exit. Keep in mind again car is really good and this can be managed with throttle, however I was curious what a few of you thing of these options... I will test some later this week as well.
1. Go down in rear spring rate to allow rear to drop faster on throttle currently on white and may try green.
2. Go down in rear shock oil. Currently at 30 may try 27.5 with the 1.6 piston
3. Go down to 0 degrees anti-squat vs current 1 degree
4. Go up in front spring rate as I am currently on green and may go up to white or gray.
5. Move battery back as it is one foam from back position now.
Being car is still rotating off corner would a role center change improve this as well. I am running Schelle Caster Plate in up position with no shims.
Thanks!

Does anybody know how much the aluminum screw kit saves in weight?

Motor position. Larger gears move the motor (and therefor your weight bias) forward, smaller gears moves it back.

What does it do differently with mm tower and flat front arm?

When I marshal I've noticed that those that are fast, when they come around a turn and hit the throttle their car launches forward real hard. Mine doesn't have that jump but instead has to build up speed. ESC is a Tekin RS Gen2 and the current limiter is turned off when running mod and in blinky when running stock, so that's why I'm focused on gearing.

Thanks. I hadn't thought about weight bias. What role does the motors torque and RPM play in the making a choice? I'm thinking a low torque motor would have a hard time spinning a larger pinion with a small spur vs a small pinion with a larger spur. I've tried different combinations and I'm not getting the results I expect.

In mod Tekin 8.5 since that's the max the esc can handle. 78 or 81 spur with 20-23 pinion. Similar prob, not as bad, but top speed is pretty good.

The upgraded stand offs still have a small pivot, but nothing like the stock ones. I will do a video and post it today.

. Got away during thwe week a few hours and hit 15-20 packs thru car but nothing this weekend.

The "swivel" of the shock on the upper eyelet is crucial for the geometry to work correctly. If the caps cannot pivot on the bushing, the suspension will bind slightly and make the car feel very "numb" on the track. The fore/aft play built into the design is normal as well and does not affect performance negatively. The only things that will cause issues on the shock eyelet is if there is play up/down and play from side to side, which would mean the bushing is worn out, but I've been driving my car nearly every week for 9 months and have yet to wear out the stock plastic shock bushings.

This really isn't a b5m question but it's the car I'm running anyway. What foams are you guys using in the front tires?? Been running a few jconcepts tires and just use the stock foam. Been fighting push in my car for the last few races and think it could be the now flat feeling front tires. Thanks

Dirt tech inserts are the way to go. Even in sale right now along with their tires. These inserts are firm at first but break in very well.
