I finally ordered a couple aluminum diff halves from overseas. I was waiting for Tamiya America, but who knows when they will stock them. I'll be on the stock plastic another weekend until they come in, but can't wait to try them and see if I notice any on-track difference.

Rcjaz has them. Just keep in mind they take a week before they ship the item.

What is the best way to tame the rear end? Mine seems to slide out on corner exit (on power).

I read some says lower the rear roll center. Then some says raise it. Confusing.

You are over rotating which means you don't have enough rear grip. I suggest either softening the rear springs or increasing the rear inner camber spacer or both.

Inner camber spacer means more shims on the bulkhead side? More shims up front or rear?

Do everyone run the center weight or you leave it out on the 419XR? How do you keep the battery from rubbing the belt if you dont run the center weight? How do everyone keep their weight down on the 419XR?

I was at a race this past weekend (and did horrible) and my car it self without a body was 1310g. With the GT body it was just under 1500g. Thats a huge disadvantage compared to other people where they are just 20g over the weight limit.

I had 50g of weight on the car (2x10g, 1x30g) I can take out, ~50g
I replaced the Orca ESC with a HW 80A justock ~10g
Im going to replace all the screws and Turnbuckets with Ti ~20g

I could save around 80g right there, that puts the car at 1230g, but without a way to to keep the battery from rubbing the belt, I might be forced to keep the 30g weight in the center.

I run with out the center weight & have no problems about them belts rubbing against my lipos. There should be another screw on the servo mount which also acts as a battery stopper. Did you installed yours? And I also strap my lipo in such a way it is clear of the belt.

Just wanted to mention that your body is super heavy if you are nearing 200g. Even my regular Tamiya NSX is about 150G. What body are you using?

419XR is not heavy but your body is. It is ultra heavy - I use Bitty m410 and painted is around 90 grams
What battery do you use?

When I do not use centre weight (on asphalt as asphalt tires are heavier than carpet ones) I put in place a small plastic servo mount block (in my case taken from TB04) - small plastic block with screw to the deck and second screw to keep battery in desired place.

With 6400 LCG lipo, MM Fleta Pro, low profile servo it is not hard at all to keep car @ 1350 g ready to race
