... At least with our system, lowering the front upper control arm mount 1" increases camber gain to 1 degree per inch of travel, raises the roll center so its in the 1" to 4.75" range, cuts down on caster change. However, it also lowers anti-dive to just 8% and bumpsteer goes up to 0.031"/inch of travel.

I make weld-on upper control arm mounts that can be used to fix or alter stuff, or use the system in a street rod, but I'm not making that change in my own car. The gains and losses are extremely minimal and I'd need stiffer springs to make up for the lost anti-dive, which means a harsher ride quality, so I just decided its not worth doing more work just to say I changed it.
I think I covered all thats been mentioned here, but if not, feel free to ask...

Thanks for responding. Been a long time!... Amazing what info you can get just asking the product manufacturer rather than assuming or going off what other people say.

If Top Heavy seems to be wanting a serious handling car so his springs should be pretty stiff. .031"/1" bumpsteer is only 1/32" and not that big of deal, IMHO. I'd take the camber gain in roll and higher roll center versus the slight bumpsteer increase...Compromises...

Would you think the loss of anti dive wouldn't be that big of deal with the lowered 1" UCA mount using a stiff spring and good shocks?

Can you fit a 275/40/17 tire on the front of your system with proper rim backspacing. Or a 275/35/18? Does the OTRE interfere with these high backspace rims?
