quick release shock mount.
 

I dont know the part number but theisgroup, (I beleive thats who it was) recommended some x-ray parts. Every time I take my shock out all I need is a 3mm. I will look tonight for the part number.

here is a pic of the instruction manual for the xray and the parts I used. Since I run an xray, I had these available to me. may cost a pretty penny if you had to buy all the parts. make sure you cut the ball cup down so that it does not bind on anything.

the plane guys have one that you can use. visit you lhs and as the plane guys for a quick release ball cup.

I use the lower part of an xray shock. it was cheap for me. had it in my pit box :)

Couple of questions
 

It has been so long since I have raced 12th scale that I need a little help. I can't remember what angling the t-bar does. For example,

Raised in front:
Raised in rear:

Now this is the tough question, what does adjusting the height of the damper tubes? For example,

Raising the outer:
Lower the inner:

Thanks guys, just need to freshen up on a couple things, hoping to make it to Snowbirds and then back to running my XB8 for the national races in 2006.

For your first question as to putting a small washer under the pivot ball? If you put the washer under the front pivot ball, it puts a small pre-load condition on the T bar when the car is at rest, fully prepped, ready to go onto the track and the chassis and rear pod is on the same plane. Some feel that by doing this you can create a little more forward bite from the rear tires. I have tried it both ways many times and I cannot feel the difference.

As to your second question about the angle of the dampener tubes, I always try to set the angle so that I get the most movement of the piston in the tube. I feel that I get the most consistent dampening that way. You may have to adjust the weight of the lube you are using. For example, on the Trinity Reflex 12, the dampener tubes, in the stock position, move very little. To get more effect from the dampener tubes on the Reflex 12, I had to use a littler higher weight lube in the tubes. On my Rev.4, because the dampener tubes have a lot of movement in them, I can use a little lighter lube than on the Reflex 12.

I have found that all of this "fine" tuning is an inexact science and that testing changes on the track provide the most significant findings. While someone else’s setup might give you a starting point, it may not be the perfect setup for you. Only when you understand your driving skill, preferences and how changes affect the handling of the car, will you be able to perform at your optimum.

Thanks, Just need to know what the basic geometry changes do is all. I got everything else covered :)

What your saying is on the tbar is,

Raised in front: Gives more steering off power and less on
Raised in rear: Give less steering off power and more on

On the damper tubes I am asking about adjusting angle on 1 particular car, not length of stroke or thickness of lube from car to car. Or did I misunderstand your reply.

Yes I understand testing is best, that is what I do, but during the week I only get to mentally masturbate (table race) my car so I wanted some material to look at.

CRC's new High Rollers?

Anyone try them yet?

My personal experience is that Jacos are too fragle for me and TRC's are up to speed yet my doors are still open for a tire company... GQ's aren't on our shores yet but an option when they do make it here.

So back to the root question; anyone try the new CRC High Rollers?

There were lots of people running them in Cleveland last week including myself. To get the car to work I still had to cut them down, out of the box the diameter was creating handling issues. After talking with Bruce Carbone he pointed out the the increased size was altering the roll center of the car too much. Once we ripped them down to 1.65-1.68 front and 1.75 rear they worked quite well. Had I packed enough ahead of time I would have just stuck with Jaco 's on the car.

In my limited mind, not bad but didn't have anything going for it. Jaco works and the new wheels are very durable, why fix what isn't broken?

thanks Nick-C for your post.

Nick-C I have a question, you mentioned that Jaco's have a new wheel? do you have a pic of it? The reason I ask is because I've went threw 2 set in one club race and was not impressed by their build.

The neon Green/yellow TRC rear rims held up great but just like any consumer I tired the Jacos and I really like how they made my car handle; however I found that the Rear rims were very easy to crack.

Now are you saying that Jaco came out with a new wheel that is mounted with the regular stage 1 compunds?

Thanks
Rudy

You have the T bar washer part correct but backwards. Just reverse your definition.

What I try and do with the dampener tubes is get as close to a 1:1 ratio of movement between the tubes and the motor pod.

I think Jaco just improved the durability of their wheels after having a bad batch of two, they don't look any different as far as I know.

Hey Rudy,

Not long ago (around the release of the 2-Stage tires) Jaco revised the material of both the front and rear wheels along with a slight design change for the fronts. The new material is much more durable, I haven't lost a wheel to it yet. The changes to the front wheel were to the inside bearing boss which was notorious for cracking very easily. The new one is huge in comparison to the old one, more material where it counts. The new wheels look identical to the old ones with just these minor changes. The new wheels are shipping on all the compounds, not just the 2-Stage stuff.

For everyone here, if you haven't run Jaco rubber in a while due to them being fragile I would have to suggest giving it another shot. For years and years Jaco has made the best tires in the business and this simple wheel strength issue prompted a lot of people to switch. Now that it's fixed I couldn't be happier, it's like having the "old Jaco" back again.

Please note that I am in no way affiliated with Jaco, just your Average Joe who hates losing a tire after one accident :)

On another note, have you tried the 2-Stage tires yet? We have been having great luck with them locally and they are amazingly durable. After a few months of racing no broken wheels and not a single chunked tire and the low wear makes them well worth a few extra bucks.

Nick

High rollers were first and second in 12th stock. They work just fine....

thanks all!

I'll try the stage duce for this weekend

Anyone been running GQ tires? I just ordered up a set of pinks and a set of tans. Going to be doing some testing. :tire: :tire: :tire:
