We are still having problems when get on the gas it starts three wheeling, and I couldn't find it in past discussions, so maybe yall could help once again. The springs lr is 200 and is behind the rearend and the rr is on the housing and is a 175. We run the lr lower link off a bracket that extends out 4 inches and is about 12inches, would doing away with this bracket and running a 16 inch link help as this would create a different pivot point? Also what would leading the rearend on the lr do? What would leading the rearend on the rr do? The car appears tight off, we have tried moving links. Thanks for any information.

I'm not sure if changing the lower link is going to solve your problem but it would probably help some. I used a Harris with the setup the way they wanted me to run it from the factory. the lower bar on the lr was longer than that, like 15 inches bottom and 17 inches top. but leading the rr will take out alot if not all of the rear steer. I had MUCH better luck driving the car without so much rear steer in it. I should have won with it the first night out and the second place car must have wanted it worse cause he used the chrome horn on me. I had the rr spring on the housing too and Harris said move it to in front of the axle shaft, when i did, i liked it much better. imagine it this way, we move the rf in front of the lf and with a 4/Z the rear should do the oppisite creating a car the is almost bending in the middle (the lr moves ahead of the rr in corner) I couldn't drive that way, so when I made the rear more nuetral, I could drive it. Try it!

Thanks for your information. We have been trying different things with the 4-z and the car right now is the best it has been but yet we are still not there. We've had the rr spring in front on a swing arm and we've had the lr spring in front clamped but it kept binding(not enough room). What would leading the lr do? Thanks, again.

If you shorten the LR, you'll gain static rear steer which should free it up, also will help it get up on the bars quicker, due to shortening the bars.

They lengthen the lr and it tightened it up on entry, they had been loose on entry and tight off. So they were able to loosen the car up some with other adjustments and the car was fast. They went to a different track this week( first time there) and finished third in heat. Was running 5th in feature when he got run over, broke lf sprindle arm. Car was still fast, we still we can't get the left front to stay down, any suggestions? Thanks

seems like your springs are soft on the rear , and what are your angles on the z link, seems with ours if you run the rear bar horizontal it wants to bring the left front up , put more downward angle in the rear bar and it stops it, on our anyway,

The car has no adjustment for the z-link to the rear, unless they redesign it, which might be a possibility at a later date. Thanks, we are trying alot of things yall have suggested.

go up on right front spring rate that will do it.

Do you think 50# will be enough of a spring increase? Thanks
