Thank you for posting this, it's exactly what I've been looking for! I currently run 15MM all round and I want to lower the car without risking any rub...

No problem 😄. And the slight rub that’s only on full lock hasn’t caused any problems in the year I’ve had them on.

Not sure if it makes a difference but I run the 18" 513M... do you know if that makes a difference or not?

Yeah you should be good.

The pic is my front wheel specs at 265/30-20. You can see my front wheel is 26.3 inches in diameter.

So try your front wheel specs to get a better idea : https://www.calculator.net/tire-size-calculator.html

How much did the springs lower your rear ride height? Regardless, lowering springs do not lower the car by an amount (1”-1.5”, maybe a little more) that would prevent you from being able to align the car to manufacturer specs. What doesn’t make sense is your pre-alignment RR was already in spec so what were they trying to achieve when adjusting the RR? Post-alignment RR camber was only 0.1 deg more negative than pre-alignment -1.6 deg yet toe went from +0.10 (pre) to -0.04 deg (post). The LR camber was -2.10 deg (pre) and was adjusted to -1.90 deg (post). Pre-alignment LR toe was out of spec at 0.01 deg and was adjusted to 0.14 deg (post).

So why was the RR toe adjusted so far in the toe-out direction? RR camber was barely touched and there should’ve been more adjustment in available camber. It seems they had no plan to adjust LR and RR specs to match. The RR camber should have been made more negative to match the LR. RR toe should’ve been made slightly more positive or not adjusted at all and had the LR toe adjusted to match RR toe. Why was RR toe adjusted to toe-out while the LR toe was adjusted to be more toed-in than RR? RR toe was adjusted the wrong way. LR toe adjustment should’ve stopped at +0.10 deg to match RR but went to +0.14 deg? RR camber should’ve been increased to better match LR camber or RR made more negative and LR made less negative to match at -1.8 deg. The RR adjustments don’t make sense (toe should have been increased or left alone but was almost made it toe-out, camber adjusted more negative which it was but by only 0.1 deg). Did you discuss with them target values you wanted for camber and toe? The results suggest there’s likely a bent suspension arm on the RR. Throwing adjustable suspension arms at the car may allow you to align your car to spec values but you could be masking a problem at the same time.

Here is a comparison between my 255/40-18 vs your 265/30-20. I'm not sure if the difference would be enough to completely eliminate rub but... hopefully haha!

You’ll be fine. I actually plan on doing 255/35/20 front and 295/30/20 rear. So the diameter would be 27”. Gonna require heating up the wheel-well and pushing it in a bit.

Sorry I forgot to ask earlier, where did you order the Euro Springs from? I've read that tunershop.com is a legit site but wanted to see where you got yours from since you just did it

Thanks dude. About to order them right now.

I know there's been multiple different names for these springs (Euro, V1 etc) but this is the article number you got, correct?
