I just talked a Product Specialist at Stillen and they said RS-R confirmed and tested that both the Q50 and Q60 Red Sports will use the same springs. I just ordered a set. For those of you waiting to lower.

:cool:

Wow this is true? Seems odd since they are different vehicles and weights? A guy from Stillen called me today and told me RS-R confirmed for him today that they are still testing in Japan and it should still be a few months before we see them here.

A Stillen rep posted on the Q50/Q60 FB group page today taking orders...so it's definitely ready and on the way.

Not sure if I want to lower yet, I feel like the Red Sport RWD versions are low enough on OEM rims without needing lowering springs....are the AWD models slightly higher? Worried about any adverse effects with the digital dynamic suspension...just don't want my ride comfort to suffer much if at all. :p

Since it is only a lowering spring you'll be able to maintain the oem dynamics of the suspension and drive modes.

As for ride quality, most lowering springs will ride slightly stiffer. I can't speak for RSR but I've heard the ride quality of their sport springs is very manageable.

THANK YOU FOR THIS!!! Order placed!! Soooo excited now I just gotta figure out whether to go with 15mm or 20mm spacers!

Would make sense after all that they would use the same springs, all I would imagine being different if there's any if some slight difference in the strut, but nothing immediately impacting how the spring mounts or fits.

At least we now know the aftermarket parts will pick up some serious pace, not nearly as much figuring out to do here :D

It is definitely better to lower then measure for spacers. The wheels will tuck due to lowering.

My guess is 20mm after springs will have a nice flush look.

How much is the drop in the front and rear for these springs?

2 different springs available.

1.4" front and 1.2" rear for the down spring. Super down springs are 2" front and 1.8" rear

I seem to remember reading somewhere on here that the AWD RS DOES ride higher but can't remember how much.

For what it's worth I've been talking to a person at Stillen (great customer service by the way) and the Q50 springs fit the Q60 but RS-R is coming out with Q60 specific springs that are not yet released

In a side-by-side comparison at the dealership, I saw no difference in ride height between our AWD and the RWD version. I can't imagine lowering this car. The fender/tire gap is as tight as I've ever seen on any OEM car.

Also, lowering a car will most certainly affect the ride quality and suspension stability by definition. You will be reducing the amount of available shock travel (damping) by the amount you lower.

A friend of mine is a suspension engineer, who runs a 3-car Porsche racing team, and is a former winner of the Rolex 24 Hours of Daytona. I've heard him comment many times that people are screwing up their cars by slapping on a pair of lowering springs without completely re-engineering the suspension.

I remember in traning that the coupe was designed with minimal wheel gap in mind. There should be no difference between Read or AWD from factory.

I have an AWD and saw a RWD at the dealer same day I bought mine. The AWD is DEFINITELY higher with a bigger wheel well gap.
I can second this.

It's been reflected on just about every model from Infiniti in the past as well

My eyes arrived at a different conclusion, but I'm not going to argue any further.

The most salient point is that there's no way I'd ever consider a 1.5" drop on our AWD car because I'd not be improving the car's performance, and likely doing quite the opposite. Looking at the gap on our AWD car, that's just too much. If that doesn't matter to you because you just like the "slammed look" better, then go for it.

For some folks looks are more important than superior performance, and I'll go with a suspension engineer's opinion any day over anything I read in an after-market spring manufacturer's marketing material or on a car forum.

Shocks and springs are designed to work together, and that kind of drop requires rethinking everything, including shocks and suspension geometry.

Half an inch
Yup, that's correct! Talked to a few folks at my dealership and a couple other people from the FB group and I can confirm that the AWD model does sit marginally higher than RWD models on these '17 Q60s by default. A cursory glance will of course not be enough to notice the difference, but the half-inch difference is there nonetheless.

I agree with Foosh that these Q60s already have some of the tightest tire/fender gap of any OEM car; even with a ramp (since I have one of those rolled, high drainage curbs) I still have to back out of my driveway at a very slight angle to avoid scratching those mudflaps/tire guards + the most extreme corner of the front bumper (I have to approach at a very slight angle as well though the front of the bumper is in no danger of hitting that way).

Just want to confirm. RS-R just make the spring for the only for the 3.0t Premium on the Q60. Will it also fit for the RS 400 RWD as well? Just want to make sure as Eibach, HR and Tein don't have it.

Thanks
