Tons of CA on the fronts. When I turn down my steering expo to ~75%, I can drive pretty hard and not flip, but when I have the expo all the way up it flips super easy.

Also seems to help when I sauce only the inside of the front tires.

I'm going to install this aluminum chassis and start fresh from there.

So here's the Reflex Racing aluminum chassis.

Stock (FRP) chassis weight - 99g
Reflex Racing aluminum chassis weight - 112g

Looking forward to getting this out on the track this wednesday and see how it performs. It looks fantastic. Nice black anodizing.

She's getting built up! All holes lined up perfectly. The floating servo mount centering hole required a tiny bit of reaming to get the mount to engage with the chassis fully, but that took 15 seconds and turned out just fine. She's coming along nicely!

Holyyyyy crap. HUGE difference in handling.

I fought traction rolling at every corner with the stock chassis, nomatter how I set up the suspension. I spent 5-6 practice days pulling my hair out trying to find a setup that would allow me to drive hard into the corners without flipping.

I put the aluminum chassis on, changed my shock fluid from 40wt to 50wt, and I'm freaking glued to the track now. I couldn't roll it even when I tried. It was just absolutely planted. Best $65 I've spent on this car yet.

I'm running this car with a 21.5 Fantom motor in USGT class, with the USGT tires, etc.

NOW, I just need to figure out how to shed some weight to get down closer to 1380g. I'm currently sitting at ~1484g with all this aluminum bling, lol. I'm thinking about trying a shorty lipo, which would save me almost 100g I think. But more realistically, I'm going to switch to all aluminum screws, run a lighter weight body for racing, and probably lose the aluminum battery mounts and just use battery tape. Thinking that should save me a decent bit of weight.

I did the same upgrading with my xi sport, instead of the aluminum chassis I am using the graphite one. Buying an ultimate would have been the cheaper option... But hey it's our hobby! 😀

If you are looking for weight reduction, changing back to the stock spool will give you around 10 grams. Most effective was changing the batteries. Coming from 305 grams to 280 plus further 10 grams of weight I had to put on the motor side before.

Mine weights 1350g with outdoor tires, and 1320g with indoor tires, both with protoform tc body 85g.

Anyone have any issues with the car veering left or right on acceleration or deceleration?

Have not had issues for the past 3 years with this car.
What is your front toe and ride height set at, and what are you using to measure it? I tried an old Integy setup station, and found it to be way off compared to my friend's Hudy.

It sounds like your car is tweaked. You need to become familiar with the general setup process. As a newby you can do so many things wrong, just because of not knowing what is basic.
Ask someone at the track to check your car and do the setup. Tweak because of different spring tension left to right, droop setup or ride high will be quickly identified and solved.

Default Aluminum Reflex chassis

On their website it says available it says brushed or sanded finish... did you have to ask for an anodized or did they come like that now

How did you manage to prevent the battery to touch the belt?
The rear central screw / brace is too far on the rear with shorty lipo.
Thanks

Add a countersunk screw to the side of the motor mount/bulkhead. It should be flush with the countersunk screw on the servo mount.

Where do I screw the countersunk screw to make it more forward ?
I can not screw it on the motor mount as it is too backward.

Do I need to drill a hole in middle of the cassis and then use a battery post or something like that?

What spring length are you guys using? I am using the Tamiya springs which are around 25mm long and I have a hard time getting the car down to 5mm ride height using factory built instructions.
