Hi Brant,
I am a little bit confused about the front roll center shims. I'm running the Numan Setup now. The 2 shims in front now are .1" total, do you mean to say that if I make them .075", this will increase my steering overall or just the turn in? I am also looking for a little bit of more steering and corner speed, that's why I think the 6deg casters are the way to go. Thanks

Sonny

6 caster is definetly worth a try, i will never go back. Feels a lot better i think.

Sup Joe!!! On my car about 2 weeks ago we ran a course with 2 180's and several rolling corners. I was trying to get into the corner harder and i did it by stiffining up the rear suspension. Then it was too hooked up off the corners. I then put in the 6 deg. carriers and it was great 1/3 into the corner untill the last 1/3 coming off. So, I softened back up the rear and took out one of the large front shims. I drove the car for half a battery at intermission and the car now had TOO much total steering. High speed and low speed and it was just a bit twitchy as well. I then went back and put in the thinner shim with the thick shim and all was well. After that race, on my way home, I was thinking that I wished I had had the time to leave the 1 thick shim in the front and try putting 1 thin shim in the rear( to tighten it up) and see how that would have affected the car. My biggest problem is we run in a parking lot and practice time is at a minimum. So far to me the car feels like if you are running the roll center at a given point ,then, you can from there fine tune its feel. If you make a change in roll center then you have like a whole new set of adjustments again. Hope this makes sense.

Gareth,

My JRX-S kit came with 4 thick (.050") and 4 thin (.035") shims and I assume that yours did too. This is enough to raise the front end pivot blocks (4 locations) to .085" as opposed to .100". If you don't have additional .050" shims, you might want to try .085" until you get (or make) more shims.

PookyT,

Nice post to Joe.

Sounds like you can notice more subtle suspension changes than I do. Should consider writing a book on JRX-S settings...No joke!

Maybe between stints of dremeling...Joke!

If I don't hit the tread mill or get SOME exercise the mountain part is feeling familiar! LOL

Bill--the Dremel as of late is in its happy place and resting comfortably. I'm saving up my energy ( and cut-off wheels) untill I start making my own rear motor chassis! LOL

This is the first I have heard of any issues with the front carriers.

I have not put it in the set-up station yet but you can see from the top looking down that the left camber link is more angled toward the front of the car. The right one is alot more laid back.

All better. I took one off my XXX-SG+.
A little grinding and it fit like a charm.
