My first XRAY T4. Never had one before. Building was really easy and the parts fit is pretty nice. Only a couple of out door races on it and for me, the car is dialed. The only thing I did wrong was installing two too long screws into the lipo plastic holders.

I have taken a moment to highlight the part differences on the T4 2019 from the 2018 for those interested.

Default 19 car questions

so I am currently running a TC7.2 and have been looking at this car sense it came out.

The local guys at my track track that run the TC7.2 donít seem to want to give much info so if Iím going to have to figure this out on my own then I might as well get what I really wanted to begin with .

So with the new car on a medium outdoor traction type track are the lowered hing pin blocks or any other option part really needed?

Please let let me know what option parts I should get with my purchase.

Thanks

Bill

You don't really need anything besides adding some weight(if your local race facility techs weight). I raced mine once stock out of the box and it was great. Then I found found out I have a lot of store credit to a hobby store so I bought a lot of hop ups, haha.

standard upgrades for outdoor are -0.75 hexes, 1.2r 1.3f roll bars, alloy steering bellcranks, and steel spool outdrives. None of it essential, car is good out of the box. But most team setups will use these parts.

Most carpet tracks are very high grip nowadays. You almost certainly want the solid Aluminum or Alum Flex depending on grip level. Carbon or Alum extra flex would not work well.

Is the only difference in the bottom deck between the 18 and 19 the screw holes for the front brace? Seems most people here don't run the brace, so wondering if this spare 18' deck I have is worth hanging onto as a spare.

The only difference is the 2 extra holes for the brace.. I have switched my 18 to a 19 chassis plate so I could run the front brace, but did not like the way it felt on black carpet.

Korey Harbke tested it this weekend, and says it has more flex than the 1.6 deck, especially in the middle / rear of the car. "Makes the car lazy and stuck." That was mod TC on a 35x80 ish crc black carpet track that was vacuumed in the morning. So medium low to medium for black carpet.

My 19 with a beat up lightweight blitz gsf, was just starting to get traction roll in the sweeper where the grip was a bit higher from friday night oval racing, but fine everywhere else. Nobody with D9s or Type S were rolling, if that tells you anything about grip level.

I had some traction roll in the corner after the straight on a carpet track. What would be the first thing to change? I was running with a 2.7 spring in the rear, would running a softer rear spring help? Or should I make the front wider?
