Xray NT1
#1967
Oh, and the track is resurfacing again today with a more aggressive sand mixture so I have no idea how we're going to make a 60 minute race at the nationals without some 50 shore tires.
I tried 42f/45r on this day, and just couldn't generate enough grip even though the tire wear was high.. Hopefully the new non-water based sealer will fix this problem.

Sounds like they are going through the same thing that the FT Myers track went through. From talking to people that have tried sealers before, the NON-Water sealer....is this an oil based sealer? The FT Myers track has solved the problem with the tire wear and lack of traction too....they dragged regular car tires around the track for an entire day (or more) to remove the sand from the track.... Traction came back and the tire wear went away...now the Fort is realy hooked up!

Sorry about that, I read my notes again and it actually reads the way you would expect.
56.9mm RF
57.6mm RR
56.1mm LF
55.8mm LR
It's odd for sure, my car should be perfectly balanced. I use the Xray balancing posts and then allow the low side to sit on a scale to measure the exact weight. Right and left are within 1 gram on the rear, and 2 grams on the front.
I then used the Xray tweak station to ensure everything was completely square there as well.
My setup was not quite ideal this weekend. Interestingly there were two left hand corners giving me a hard time where I felt like I needed more turn-in and usually ended up washing the front a bit which would have increased my RF tire wear. Toward the end of the race this eventually caused a slight spin as the tiny LR tire because the droop setting changed by so much.

I have the same wear (very close) exsp. the left side of the car wear a lot because of the high speed left corners.
This is what I do for 1 hour mains.
BEFORE AFTER
LF 61 mm (40s) - 56 mm
RF 60 mm (38s) - 56.5 mm
LR 63 mm (42s) - 55.8 mm
RR 62 mm (40s) - 56.2 mm

For shorter mains is my advise : 0.5mm left/right split and 1 mm front/rear split .

Hi there, i just bought a nt1.
It's the car which jilles drove the winternats with.
I'm very happy with, it has a lot of options and spare and the car was a bargin.
But there wasn't a manual and other documentation included.
So i wanted to order it but i can't find the part numbers for them.
Does someone knows them?.
Thank you.

You can get them online for free here on the XRAY forum.
i think xray don't sell them apart from the kits.

What bearing oil are you guys using? Considering that the instructions expect you to oil the bearings before installing them, I'm surprised that it is not included with the kit.
Anybody just decide to swap out the bearings with another brand? If so, why?

Bearings in the kit are pre-oiled, no need to do anything with them. For maintenance I use mobil 1 synthetic oil...

Today i drove my nt1 for the first time.
It handles very different then the 720. Feels much smoother and the car handled like it was on rails.
Wasn't faster yet then with the 720, was still .2 seconds off.
But i only did 60 laps today.
Tomorrow i will race it for the first time, so then the track will be much better and the car is still really understeering which is easy to fix.
