We're still learning a lot over the diff behaviour, and driver feedback is precious to us.
Heavy oils like 1 million, give a solid car, probably a touch too much on the safe side. On the other side, I'm testing teflon coatings. Car is a touch temperamental, but wicked fast.
500K seems to be a good all around for most of the drivers. Did you used the newest Titanium axle with the larger spur?
I used the smaller spur gear, but I used the same rollout I used when running a 96 tooth spur. It had a titanium axle. The top three cars all used the gear diff. One used 100k, one 300k and I used 500k that way we could compare results when we were done.

I have the gear diff. Have not found faster lap times on any of the four tracks I race on, one massive 1/5 asphalt high grip, one big asphalt 170' high grip, one tiny asphalt low grip and one carpet, using gray crc carpet.

Have tried 100k,300k,500k and one million. Also tried Pits and ride xr.

Just makes car alittle less forgiving on late mid and exit

I have been able to do back to back runs using the gear and ball diffs. The tracks we run all have CRC black carpet. It was a couple of tenths faster and more consistent over the run. This was using the same layout that The Halloween Classic was run on. We will be using the same layout again the weekend. We also run either TCS tires or CRC premounts. The tracks are usually in the 90 by 40 foot range with high bite.

I just picked up a used X1 that is set on an aluminum chassis, I run predominantly asphalt, should I switch back to the included c/f chassis or just run it, thoughts ?

Jeff, you can try the aluminum chassis but the car maybe too stiff and not provide enough traction for our asphalt surface. You will eventually switch to the carbon fiber chassis and find that the car will work much better.

I kinda figured that, the car was only run on carpet so the c/f chassis has never been run so I'll just swap it out, thanks Andy.

If your looking to get rid of that Aluminum Chassis, if it is flat, shoot me a PM.

I'm still using 500k in mine. One of the guys last Sat was running black grease in his and it worked well. I don't think I would go lighter than 300k. The diff just seems to make the car easier to drive. The other thing that has helped is the aluminum chassis. I need a practice day. The Gate is only open on Sat and you just don't have time to try a lot of things. Sorry, not much help. Do I think the diff is worth it? Yup. We'll find out in two weeks at The Indoor Champs. Close to thirty F1 cars entered.

hello everyone. i'm new with F1 cars but have some experience with 190mm. i've some questions for you.

1- with the touring car running 13.5t motor the lap time it's about 17 sec. what FDR should i have for my F1 to accomplish this same lap times?

2- i'm using the stock ball diff but if i set the brake 100% end point the car will slip and turn on ti's self, but if i lower the end point that effect disappear but the car now wont brake. it's that normal?

3- have you ever used GRP formula tyres?

4- how important it's tyre additive.

car and track info.

HW justock esc justock 21.5t
shorty battery

track it's asphalt low to medium grip without any kind of additive to the track or tyres.

thanks

Tyre additive depends on the track & weather, but we never drive without tyre additive.
GRP F1 tyres are great, they are the BRCA Control Tyre in the UK. Very good quality wheels & rubber.
