Fellas!!!! Has anybody done any testing on carpet or asphalt with the rear uprights or stand-offs removed????? Just wondering what a little more rear chassis flex would do????? Lets hear it??? Bill--I bet you have tried it or know somebody who did!

Pooky - SoCal and 4Fun running for me is no standoffs. Asphalt needs a little more flex to generate more traction.

Even though I missed the A by .4 seconds, I have to take responsibility for the two bobbles early that cost me just over 4 seconds(TQ was about 5 seconds ahead of my final time), plus the time I wasted being nice to a driver with an overheated motor towards the end for almost 3 laps..........
It's nice to know my car is capable if I use it to it's potential!....next race is at Superior Hobbies(Corally home court). I'll run mod rather then expert 19T, HP won't be an issue with an Orion 7 turn, LOL!...............Jim

P.S. My racing buddy
Was running a TC4 but he had all the traction in the world! In the main his car was squealing aroung the corners. I did win the main but it was a handful to drive!Ok Well it won't let me up load the PDF file so If you would like to hep let me know and I will e-mail it to you.

RC Old Man, my e mail is [email protected], i'll take a look if you would like.
The race I ran the Numan set up on, was held on a fairly large asphalt track, with medium to high traction, sweeping turns and 2 chicanes, as well as a few keyhole turns and 180's. A fast lap in 19T was high 18's, my best was 18.7, a few guys hit 18.6's, but not many.
If your track needs less steering i'd try removing one front roll center shim, so you only have .050 added, then if you still need less, remove the last shim and try again. Of course you'll be screwing and unscrewing all kinds of set screws, but we wouldn't be racing if we weren't wrenching, LOL....Jim

For steering feel, it effects how much of the tire contacts the surface during turns/chassis roll thru SAI. There is also the weight jacking that occurs because of the axles change in inclination, etc.
Commenting on the above quote, for our purposes, SAI and castor angle are the same thing.
The reason castor tuning seems elusive to some, is that it is directly effected by chassis roll stiffness. In other words, less roll in the chassis will like less castor, more roll will like more castor. This is because of tuning and not the surface itself, since tuning can reduce or add roll on any surface if desired......., Hope this helps?.....Jim

So I'm not arguing with your statements Jim, just commenting on them.
THnx for the input!!

Turnbuckle wrench
I work in a machine shop and am going to make some turnbuckle wrenches for the JRXS since it is a smaller size wrench and you have to use that skinny little thing. Im just wondering if i make them, will anyone be interested in buying one, it will look similar to the Lunsford wrench. Prolly sell for 5 bucks plus shipping. Let me know...
