Eibachs and Macht Schnell Spacers on SG E90

JH M3 · 06-18-2010, 08:15 PM

Had the Eibachs installed along with a UUC SSK Monday. Thanks to the guys at Sonic MS. I'm very happy with the mods. The drop is the way the car should have come from the factory IMO. The ride in Comfort feels softer on the highway, but I can definitely tell that the springs are stiffer going over bumps at slower speed. Got some before and pics after I installed the spacers. 15mm front and 12mm rear.

nice. thats exactly what I plan on doing by end of summer only probably get slightly larger spacers. how do u like the eibachs? they sound perfect to me for what im looking for, but i don't like how the rear kinda looks lower the the front. not enough of a stagger I guess you can say. but they seem to be the best out there based on reviews.

JH M3 · 06-20-2010, 12:05 PM

Love the Eibachs so far. You actually get a little more rake than stock since the Eibachs lower the front .3 inches more. It always bothered me as well that there was more fender gap in the front than rear. Ride is better in comfort on the highway, but I can definitely feel the increased stiffness at slower speeds. I'm going to wait until I get an alignment to make a call on the handling.

There isn't a staggered fender height, your front tire is a half-inch shorter than the rear.

OP: keep us updated after your alignment...is Sonic doing the alignment also?

That's my plan, although its kind of a haul for me. I may end up going to Performance Art in Gilroy since they are closer.

IRMthree · 07-07-2010, 05:22 AM

OP: update? has your eibachs settled lowered a bit since install with more mileage on them or the same?

JH M3 · 07-07-2010, 05:09 PM

I would say that they have settled a little more. I've got about 500 miles on them. Getting an alignment next week. I'll post pics when I get a chance.

JH M3 · 07-07-2010, 08:55 PM

Here are some before and after pics. The before pics are after about 100 miles. Maybe just a slight settle.

IRMthree · 07-13-2010, 05:08 AM

thanks...btw, what tint % do you have?

I just had Sonic install my springs and spacers. RStechic 15/12 and Prokits, with the E36 M3 bumpstops. Looks great and they did a great job.

kitw · 07-13-2010, 06:03 PM

my springs look lower because of the sun, I think they are actually the same ride height as your's.

yeah, but only 0.25 inch of that is above the axles. There is a bigger fender gap up front.

I know that. Measure the distance from the center of your hob to the fender. It's the same front and rear. The gaps are the same.

kitw · 07-14-2010, 02:20 AM

^ mine definitely aren't with the prokits.

Mine have only been on for a day, but I'm at 14" in the front and 13.25" in the rear. only 0.25" of that is accounted for by the tires.

That's because your car is lowered...

On my car, the factory ride height had a similar difference. 14.75 and 14.25 was the difference stock. (which was more than the 0.25" of the tire difference.)

Sedan vs Coupe difference?

quality_sound · 07-14-2010, 12:56 PM

Did you measure to the ground or the center of the wheel? That would explain the half inch difference.

Sleeper519 · 07-14-2010, 09:26 PM

Mine is 14.0" rear, 14.75" front. Coupe, 19s.

quality_sound · 07-14-2010, 10:38 PM

Maybe a running model year change? It's possible it's a body style difference but that really wouldn't make any sense, but then again neither does using a different side gill on each body style.

From the center of the wheel to the lip. I measured another 2011, it was exactly the same.

(Ironically, my wife's 335i is even front and rear, but the overall diameters of the 335i are the same.)
