Hi Tom,

Like others have mentioned, that is pretty big tires to run, especially with a 4mm ride height.

Before you start chasing car set up, I recommend truing your tires down to 1.75" rear and 1.65" front and see how your car handles with that.

I also meant to ask what traction compound you are using and how much you are doping the front tires? I recommend starting with full rear and less than half the inside of the front tires.

2) The Jaco Prisms are rounded quite a bit right out of the box.
3) The ride height was set to 4mm all around.

Thanks.

I ran the car completely stock as Jason wanted it. I didn't want to dilute his work with any accessories until I drove the car. I thought the car was great. Since it's the standard IRS axle, you will want to use the #101 Thrust kit.

These are the same numbers I find best to start from; least chance of ripping chunks and good mass to height for longevity. Brian tells the truth on the tall tyres and stripping them off the rims. I run a tiny CA beard on them brand new.

Sounds good Rich. Earlier this evening I cut down a set to the 1.75" and 1.65" dimensions.

For your question on traction compound, I'm using Jack the Gripper and have been covering full rear and the inside 2/3 for the front. I would let it soak in for 15 minutes and the wipe it off a few minutes before running it on the track (CRC Carpet). I'll try your suggestion and cover less than 1/2 of the front tires. How long should I let it soak in and when should I wipe it off?

As previously mentioned in one of my earlier posts, I went ahead and rebuilt the flex-plate assemblies on my car. I noticed that one of the set screws used to eliminate the slop in on the pivot ball of the flex plate had loosened up. In fact, it was at a point where it would not tighten up properly without locking up the pivot ball movement. I replaced the flex plate with a new one and everything is good. The rear pod is now parallel to the main chassis left to right.

I also replaced the steering knuckles as there was too much slop in them. A big thanks goes to Dave Arnold for some additional tips on fitting the steering knuckles to the king pins for free movement and no slop.

So with the newly trued tires and the suspension repairs I mentioned, I put everything back together and set the ride height to 3.5mm. I checked it on my tweak station and everything looks good.

I'll be running it this Saturday so we'll how it performs.

Thanks,

Ben,

I got the car buddy. I went through it and found a few problems. The front arm screws were cut short and the front arms were pretty unstable and gave the car about 1degree of arm sweep. I replaced the screws and put a set of my new arm shims in there and now the arms are solid and there is no more arm sweep. The rear axle shimming you fixed and that was good. The car was unbalanced. That is one big speedo buddy Its a nice one though. I moved the switch and transponder and added 8 grams to the right side and now that is good. I rebuilt the diff, changed the front springs because they were collapsed, The set screw for the ball tension on the left side flex plate needed to be screwed in about 1 turn which made it have play on 1 side giving it a tweaked effect. I srewed the one in and set the play in both sides even and took the set screws out of the flex plates to make it a little softer. The car should be DIALED when you get it back. She is all finished and ready to be packaged back up.
