604 Crate still a little too tight

This winter have the new style cross member put in. It makes a world of difference. Until the rocket makes drop spindles to help with the bottoming out

Just an update on this... we raced at a new track to us this past weekend since the UCRA crate race at Cleveland was rained out. About the only changes I made on the car from what I posted above was lengthen the RS bars each 1/4", lengthened the J-Bar about 1/4", moved the LRT rod down one hole, RRL rod up one hole with a 450lb LF spring. The track was a 1/3 mile high banked with no inside or outside walls. The track was pretty tacky but had 3 grooves to race on.

Usually my car is very tight when it's tacky at all but it felt very good. Didn't have to slide the brakes to get the car to rotate, but just used a good bit of pressure and as soon as it rotated, I was on the throttle all the way through the corner. Good forward bite off the corner and good side bite in the center of the corner. I only pushed a couple of times in the feature but I felt that was more due to driver error.

Doesn't lowering the upper bar on the cage tighten the car by limiting rear steer?

2006 is a raised rail car. It shouldn't be hitting. But I bet it's bottoming out on the front bolt of the lower. Put a 250 on the RR. What is comp. And reb. On RF? Also try a 1 in spacer on the RR. What is the tube length on the LR?

Yes it's raised rail but not raised crossmember which started in 2013 on the Blue Rocket. Most before that will run a 1" puck style bump to keep it outta the track. If you think about what a high banking track will do to the LS which will in turn effect the RS clearances it makes sense. He was flying this weekend though. Rocket raised the crossmember for a reason. They also designed a tapered bumper and raised the bumper mounts to keep that out of the track too.

I know what they did and why. He said his frame rail is hitting not the cross member. I ran high bank in an older rocket. Frame never bottomed out. The bolt on the front of the upper always dug in. Ended up cutting the mount down and grinding the head of the bolt down to stop it

Kwoods25, I assumed earlier this year that it was my frame rail that was bottoming out... but it's most likely that was wrong and it's been the cross member. I changed my shock settings too on the RF to try to keep it out of the dirt and that has seemed to help it some too.

[Kwoods25]

Even with the new style cross member they are still hitting the track. It did help some. But my aluminum plate at the rack is beat all to pieces from bottoming out. My 2011 car kept hitting on the lower bolt up front. We rigged it up to help it. But it still did it. Just the norm for rockets

Good to know... I'll be going to Duck River this weekend to run with the crates on Friday night and then to another local track to me on Saturday. I plan to use about the same baseline setup that I used this past weekend and see how it goes. I've not been to Duck River before but I think we'll do ok.

[Kwoods25]

Good luck to you buddy

Next thing you know they will be raising it again....I hope they fix some stuff that orange has been a huge disappointment to us. I really have always liked rockets but the past few years they have been a lot more work then some of the other brands to get fast out the box
