im looking for a little tuning advice. on my local track its high grip clay and im im getting a lot of front end diving and wheel chatter up front and a little push. im at 30mm in the front and 28 rear for ride height . I have the grey spring up front and white rear and 32.5 shock oil. should I be using a higher shock oil?

Higher weight oil in the front will help. I believe I am at 37.5 now.

I've raised my roll center in front (no washers under the inner ball stud and short link). Are you running the 3 gear yet? That helps reduce some of the movement front to rear on and off the throttle and brakes. I should be looking at this from a different perspective: diving and chatter are symptoms, not the performance problem. What part of the track is the truck not performing in properly that is causing you to lose lap time?

Mostly on really tight corners I notice it . The rest of the track It feels good other than diving a little more than I'm used to. No 3 gear Trans either.

Quick question...

What's the handling change or ride characteristic of running 0 offset wheels vs the +3 offset wheels? Are there any 'yes definitely run 0 wheels' in certain cases?

Thanks!

Jake

If it's really high bite lower your ride height . This does wonders for the truck. Also the 3 gear really helps. I'm at 35wt up front with the 1.5 pistons.

You will reduce your track width by 6mm. I'm not sure about the physics of it other than you're making the truck more top heavy by raising the roll center. Its not necessarily the worst thing that you could do but my truck feels better wider and I don't think it needs any additional steering. If traction is low and you can afford to raise the roll center it might not be that bad. I dunno. I'd just stick with the +3s.

I read up. What I found is that wider track will tend to reduce the load transfer to the outside when cornering, which in general will increase cornering power since you'll be able to get more traction from the inside tires. So once again, increasing the track will tend to reduce understeer.....so making the car narrower will increase understeer. Contrary to what I thought it might actually reduce steering. Last, by narrowing the truck you will also change the balance front to rear as you change the ratio of width & length.

When using the "middle" hole on the rear arms, can the arms be used interchangeably?

they are on their webpage


Also, cav said he pretty much always runs the same setup with small roll center changes. He most tunes with tires and just drives the car. The pros spend more time cleaning cars, than tuning them

I'm running 3x1.4 pistons with 32.5wt. Not sure it's needed though. I just wanted it close to my sc10, which is still a bit faster.

3.5 rear toe with the brass hinge pin brace, stiffer front spring and oil...otherwise, the correct tires for the track. I'm running a short wheelbase with the 3 gear and I can put down power like crazy. Brick pack all the way back. I'm running on relatively good grip indoor clay. I have a new set of Panther Rattlers on that have great grip but are wearing quicker than the MC Electrons that I had previously.
