I like the black carbon ones because they look better and are stronger than the nylon ones. They may more brittle though but I have no hard evidence of that.
so I guss I need to use the set screw behind the nylon ones ? I am not seeing the need for front springs if everything is locked up am I missing something here?I was thinking the front axles need to be free on the king pins to take up the bumps..thanks everyone for the help and info I will get this F1R rolling yet 7 years on the shelf is to long...

Ok, you need the setscrew in the upright to hold it to the kingpin. The wheel, the upright, the kingpin, and the upper arm all move as one when the suspension compresses. The bottom arm is stationary and suspends the front of the car through the the spring at the bottom of the kingpin.

Ok thank you I see what you are saying now I will do that and maybe put the carbon upright in also I already put the kit shims back in. I think the carbon will be okay here in Florida.carbon may not do to good in the cold weather.

What kind of spur gears are you guys using 48p or 64p gears? I have 69/23 48p for a FDR of 3.0 outside track 25.5 motor or do I need to get pan car gears? Thanks

I race outdoors so I use 48p. Saves money and headaches in the long run

Ok thank you I agree,a lot of people here run 64p say I can't keep up because of the 48p.in my touring car but my FDR is not that far off from there's.I tryed 64p in my TC did not like it spent my day picking out rocks from the spur gear LOL.

If you run 48p gearing and get close to optimum fdr(close to the guys running 64p gears), then you need to play with motor timing to get back on pace.... We know 64p has closer ratios than 48p but you can compensate with higher or lower motor timing values to get the same results.
In addition, the 48p gears will keep better efficiency longer due to their durability vs 64p.... The 64p racers will need to keep changing their spurs every week to stay ahead, while you can run one 48p spur gear for years without any issues....
It is always the racer's call, but I only run 48p or 32p for all my cars, bikes, trucks, etc.....

What would be a good ride height for F1R on my touring car I run 5.5mm front and rear?what would you recommend for a good motor I have a 25.5 hobby wing? If I remember right the F1R likes everything soft oil and springs. Will a full pack or a shorty battery be better asphalt large track grip is medium to medium high sorry for all the questions thanks

Hope to test and tune my older f1r in a week or so.so far very happy with the new parts and the look of the new front end.also been looking at other models of F1s they mostly look the same in the front. I like the F1r3 the best out of what I been seeing from other models I like the ifs front and the t bar rear I think it is best for me on a asphalt track I don’t run carpet tracks at all. I am to build it from the ground up the club is running 25.5 motor.any tips from you guys that have the F1r3 how do you like it on asphalt tracks I just don’t want the same car as everyone else has from what I been reading about all these other models the f1r3 is a better choice I think.thanks Jerry

I'm running my F1R3 on asphalt. Standard front suspension, not IFS. Once I went to softer side springs and a soft center spring, it really hooked up. This is with a 21.5 motor, on CRC tires.
