I see on Ralph's setup that it lists a Jaco 32 front tire. I have wanted to run the 32/35 tire combo and use Jaco on my 1/8th but they don't have a 32 compound listed as one that they offer. They only seem to offer a 30 or a 35. I think Jaco needs to get rid of the 30 and make a 32 front tire. That would be great.

I see that Ralph's set-up shows a MRX4-R rear upright. What is differant on that from the X rear upright?

What does the rear universals help the car?

I ran the R uprights and upper arms a few times last year (Mike's suggestion) and noticed more rear side bite. It also kept my car from over rotating during hard cornering.

Which ones did you run the last time at 301? Your car was very fast.

The part# for 32 front's is JAC3732P (prism wheel).
Whats up Doc.? The hole in the X up rite that the set screw 3X16mm screws into has been moved in toward the center of the chassis 4mm, shortening the length of the upper arm center to center. The X up rite with both of the bearing shims on the "inside bearing" still has the center of the contact patch/ traction circle .5mm further away from the center line of the lower pivot balls. The simple...4 or R up rites will produce more rear grip.

Jaco does make 32's but no one seems to carry the things. They can be hard to come by sometimes. 32/35 really works well at a lot of tracks.

Never tried it there. I will be running mostly sedan this year, but I'll roll out there and help out the X crew.

I've been using the set up posted by Mike for the last couple of weeks now at CP so It should be a pretty good base line set up for most places...
The only difference is that I was using R hubs and different tire compound...

Are you guys just running the R hubs or do you have to run the upper arms from the R as well?
