SPL said this to me...
Number 1 I would replace the tension rod, which is where you have that BMR lower control arm bushing, but if you are planning on getting the Vorshlag camber plates, you MAY be able to get the castor you need, but it only has a few settings for castor, it is not on a slider like camber. Otherwise, in order of importance 1. Front lower control arm - Roll center correction and additional camber 2. Tension Rod - Castor adjustment, elimination of play in bearing up front 3. Rear Upper Camber Arm - More rear camber

No, the other way. Positive caster is the rearward tilt of the steering axis. Because the wheel centerline is above the lower ball joint, the caster change can cause the wheel location to change. How much it changes varies based on amount of caster change and physical location of the lower ball joint and the wheel center.

But, If the top of the tire moves to the rear, then caster will increase.

Perhaps a key here is where such movement would be measured. A bit surprised, that's all. |

In any case, if the wheel did move rearward, presumably this would have an affect on F to R weight distribution (and not in a positive way imo). All in all, interesting discussion. Apart from rear toe part, not quite sure how all these $ translate into faster pace, or better tire wear, etc. Cheers! |

Here is my 1LE, +7.2* top pic, +9.0* bottom. notice the gap at the front of the tire to the fender edge. The tire is pulled forward with the +9.0*. All of my caster gain is done at the radius rod (Gen6 ZLE), but if I was able to add more at the top, again, as in Scargoes case, the top of the knuckle would tilt more, pulling the tire rearward.

Thanks guys, yep that makes sense now.
And yep, what the bottom pic shows was my expectation hence my original reaction. NB Obviously, i get the benefit of the rear toe link. Not sure i would conclude that an increase in caster automatically negates a weight ratio difference, but i suspect it all depends on what one is after. Thanks for the added explanations - appreciate it! Cheers! |

Increased caster will help with return to center but the most important thing, especially on a strut car that loses camber as the suspension compresses, is the camber gain when turning. 2* doesn't net you camber gain vs stock but reduces the amount of camber lost in corner. I also noticed a decrease in the amount of understeer on tight corners at the autocross. I haven't noticed any drawback to applying power like this but I also have the alternate eLSD tune.
