haha, yeah, my hobby store owner said it would be no problem for him to true them for me, but if possible, i wouldnt want to bother him more than it is. I do have the prisms, and i noticed when i got them, they were pretty close to race size, and looked fairly close in diameter, i might check em, when i go upstairs.

I start right about where the Prisms start...48mm rear and 45mm front. With Jason's new "lowered" lowered rear plates and the IRS front arms you really can run 'em until you see white. I don't generally go QUITE that far, but I know a couple people who I'd SWEAR are running on the contact cement that holds the foam to the wheel.
Once they get to about 44R/42F or so I like to put 'em aside until the next big event.

Hey buddy,
Have sal give me a buzz. He hasnt ordered them from me yet. THese front springs really are a must have. They keep the car extremely flat and carry a ton of cornerspeed. They also do not collapse. We preset them to there size while being made. One set will last you until you lose them

What is going on with these new springs that eveyone has been talking about? What is different about them? What spring rates to they come in?
Thanks,

Hey Jeremy,
What we did was make a larger diameter linear spring for the front end of 1/12th and 1/10th pancars that will never collapse.
This helps make the front of the car roll more evenly with the rear. A big annoying problem in 1/12th cars is doublesteer or push. This is caused by the chassis toucking down in the corners. For so long we have been trying to make the chassis more narrow to solve this. We were attacking the wrong issue. Thinning the chassis more did not help. What we needed to do is let the lateral weight transfer be absorbed by all 4 corners of the chassis as opposed to mostly just the rear. Being that the weight transfer in the corner is now being absorbed over a larger area, the car overall stays flatter and the chassis will not touch down. This will increase cornerspeed,transition speed and also eliminate the doublesteer or push.
The springs do feel softer than the AE springs when you compress the front with your hand. You will find the car doesnt bottom out like you would expect though. Overall, it helps to give a balanced feel to the car and increase performance drasticlly. The springs are available in .020, .022, and .024. I may try .018 but i think they may be a little soft. Let me know if you would like any more info buddy.

O.K. ya sold me!
Now here is my next question. Are you guys still running dampening lube on the kingpins with the new springs?
Where can I get these? Your sight is down.
Keep up the great work Jason. Everyone I have talked to who runs your stuff says you are a great guy. They say you are very passionate about R&D.
I see your team is begining to place very high at the latest batch of major events!
Keep it rolling man.
