Welcome Nick! Most 1300/1340cc cars start with a 16T front sprocket (suspect you could be 14/15) then rear from 41-46 ish. 16 on the front and somewhere in the middle on the back would get you going a...

@speedsmith @charleyhradicalsportscarregistry-com Wow. That's a real pearl of information! I've ALWAYS set my pedals up so that at maximum braking, the throttle was about level with the brake -- which...

Thanks Charley, it helps to at least have an explanation for why the pedals are designed the way they are. I'm a left foot braker so there's really not much risk of accidentally hitting the throttle ...

@rjbender Thank you Rod!!!! I really appreciate you taking the time out of your day to take this measurement. I looks like it will work perfectly. I have read so many of your posts over the last few m...

@bird - G'day from Tasmania! Just reinstalled the rear wheels on my RSX and the Radical supplied tie-down inserts to measure this for you. 1850mm (just under 73") is the exact width of mine.

I did a ride height reset and complete setup yesterday. Mine was off by 166/196 pounds in the front/rear corners. I split the adjustment evenly between all four pushrods, never touching the damper s...

@davidf Thanks very much for all that info. I think I've got a decent brake shape, but my goals this year are to add more trail-braking and to move my brake points deeper. I've always felt just a bit ...

@parsonsj Hi John. I have to look at my data for the percentage, but 60% sounds familiar. Sitting in the car, you can set your initial bias, but generally you want tune the bias on the track so tha...

Yes, for a typical turn in, I stand on the brakes initially, and then I am coming off of the brakes as the brake zone ends, still holding some amount of trail brake as I turn in, and then completely o...

David, thank you, that is a fantastic list. Re: Car, I have a 2022 SR3 XX, was produced just before they made the switch to the SR3 XXR. Will get to ordering the parts above Kevin

@davidf David, that's a great list of suppliers, tools, and hardware. I have nothing to add, other than to extol the virtues of Milwaukee 12v (not the 18v stuff, they are too big!) tools, including th...

I looked at some of my Belmetric orders, and I used grade 12.9 for M5 and M6 bolts. 10.9 for M8. Honestly, I don't really know what is required but for the smaller screws they are all 12.9 at Belmet...

The suspension bushing bolts and nuts are 3/8-24 size. I bought 40 of the nylon insert locknuts from McMaster, grade 8. part number 90630A155.

@frank Let me echo what Charley said. I'm using Geartronics components (compressor, accumulator, shift valves, etc.) under MoTeC control.

@fsts2k Hi Kevin. What model and year Radical did you purchase? I am familiar with SR3 only. The fasteners you need depends on how much work you plan on doing yourself and how you drive. The ma...
