What is everyone's thoughts on the front mass damper?

My opinion is bumpy non permanent carpet tracks. The type that get rolled out on gym floors for example.
Also can benefit a car that chatters the front in corners from low traction. (though tuning adjustments are a better choice)

Gains seen on low/med bite bumpy tracks, not much benefit on high bite smooth tracks.
Worth having in the pit box though. Quick easy trial and error tool.

Would you mind posting your setup?

I am having this issue as well and I still haven't found a good solution. I basically added a long M3 screw with spacers on the steering arm as a stopper but i am sure the extra weight is not helping my handling. I was running GT12 at my local track and we use USGT motors and fixed gearing. been having a tough time getting the weight down to 720. switched to the CF chassis, U7936 Titanium King Pins, and U7937 Titanium Front Axle and I'm still over weight.

I drilled the lower arm and used U7938 chassis posts as stoppers on my Eclipse 4. I can't figure out why this is not an issue with my Eclipse 3.

We run USGT motors and SJT rubber tires. I'm currently at 756 grams. Here is what I have done to save weight to my E4:
- C/F chassis
- All titanium screws, kingpins & axles
- GensAce Redline Battery w/ 4mm plugs
- 18-gauge wire
- Core RC C/F spool
- Sanwa servo
- Montech Akura body w/ light paint
- CRC front & rear body mounts

Sanwa servo, small esc, and 16 gauge wire is a must.

Some of the batteries are 5 grams or so lighter as well but that isn't a make or break.

If you use good screws it will enable you to place some ballast and dial in the balance. I would go overweight anyway just to get perfect LR balance. Makes checking tweak a no brainer.

Do either of you have a GT12 setup sheet to share? Always looking for setup advice.

IIRC I saved 10 grams going from 16ga wire to 18ga.

Good call out on the ESC bmwjoon . I use a HW Pro Stock 1S.

Mantoya I'll upload a setup sheet tomorrow.

I used Jesse Anderson's set-up as my base.

Here are the differences:
Body: Montech Akura
LiPo: GensAce Redline 8000 1S w/4mm bullets
Motor: USGT
Spur Gear: RW Racing 63T
Pinion: Arrowmax Super Lightweight 63T

SJT Sauce Time: 2 mins: ¼" from inside for fronts / full for rears
Sauce: SXT Lite
Sidewall Glue: I glue the fronts because our track has really high grip

Front Ride Height = 3mm
Caster: Depending on track layout (tight, open or mixed) I can go from 3-5°. Currently at 5° for a mixed layout with only 2 tight corners.
Droop spacers: 1
Toe: +0.5°
Inside wheel lock: 20° - got this tip from John Barron II on the FB

Rear Ride Height = 3.5mm
Rear Axle = Spool

Post back here to let us know if it works for you.

this can't be on the up and up
