Default IS350: H&R Springs

Installed the H&R Sport springs for the IS350 (Model #52428).

H&R Webpage for springs: IS350 Sport Springs
Ordered from Allsprings.com: http://www.allsprings.com/ (would recommend)

Ride is excellent, very tight and controlled. I have had Eibach on my previous two cars and I like the feel of the H&R much better. I could be making things up but the braking feels more responsive too.

The pictures suck because I used a crappy compact P&S and the lighting wasn't perfect.

Looks real good man! Did you have the sport or standard suspension prior to the drop? Hows the ride compared to stock?

Looks great. If I didn't have coilovers those are the springs I would run.

I had the standard or non-Sport model springs. The ride is much better than stock with regard to feel. It is very pleasant over "normal" bumps but when I run over "city-*******" you can feel the sharp compression quite a bit. I would recommend the springs to anyone but if you are hesitant, go to a meet and ask someone for a ride in an IS with lowering springs installed.

I like it alot.. I wanna get roadmagnet spring (2 inches around) and I know the drop will be even but the rear look more lower then front.. The H&R give a nice drop and I see the front lower more then rear..

Here is the pic of MrMARk ride with stock rims.. I see 2 finger gap in the front.. I thought 2 inches drop cover the gap all around..



See the front have a little big gap:



IM thinking about put Road Magnet spring for front and leave oem spring in the rear.. So the front can lower more and cover fender gap...

That's a good drop. These are linear springs, right (not progressive, which I think Eibachs are)?

Does the car feel "bouncy" over imperfect roads?

The H&R Sport springs are progressive, the race springs they sell for other applications are linear. The roads are pretty good where I live but I wouldn't say the cars feels "bouncy" on any road.

Awesome, glad to hear that.
I know that on the 335i, H&R springs, while providing a similar drop, make the car feel bouncy and actually less stable. I don't know the spring rates, but they just aren't matched well to the stock shocks.
Nice to know that isn't the case on the IS.

Body roll is not just side to side, it's front to rear as well. Stiffer springs would most definitely feel different when braking, moreso when braking hard.

Exactly, no nosedive = better braking (keeping more force on the rear wheels)

Mainly a better braking feel but it may have like a 1ft improvement over stock in 60-0 braking.

Did you use the stock structs/shocks to replace them with aftermarket ones as well?
