Something that's come to light that's pretty interesting and may have more effect on the an Long Travel set up than anything else.

I've just had the new set of Chromo lower control arms put on from All-Pro and the toe was set super in before the alignment.

I drove around a bit as the alignment wasn't scheduled for the next day and found I had almost 2" more of lift than before which was strange as the coil-overs weren't adjusted but I did recharge the nitro back to 200PSI.

I messed with the coil-overs as I couldn't figure out why the base setting kept fluctuating in a really big way!

I had some serious bro stance!

I thought it was strange that the front was so high from just nitro recharge. After having JJ drive the truck forwards and back for me I saw the front rise going forwards and then drop going backwards. It was the toe setting and not the suspension! Geometry had pushed the wheels closer together forcing the front end to rise!

After the alignment I had the toe set slightly positive from previous set ups but even now the slightest toe is still forcing the front up about an inch!

Toe setting is now very close to zero and perhaps this will solve the want for the Tacoma to get bro stanced out!

So if you're having a hard time with your suspension set up and baseline check the toe setting as it can impact the baseline set up of the suspension.

Thats good to know! maybe I should get an alignment done and that might be the cause of my serious rake....

Toe-in will give you front lift going forwards and drop the front going backwards

Toe-out will do the opposite, front down forwards and front up going backwards.

Also, just remember that it's best to always have a slight toe-in because unlike the rear end, the front end of a truck consists of bushings, joints etc and as the speed of the vehichle increase, the wheels are forced slightly backwards and "open/ toe-outwards" due to tire friction and the "give" of the bushings. In stock vehichles this setting is simply based on the specs provided by the manufacturer which is based on high speed measurements, but in an aftermarket set-up, this may vary. If you don't have the wheels toe-in at rest, they will not be straight at speed, but toe-out, causing tire wear and handling issues.
