    Yes up to 19x9.5 ET 35 will be good to go, I will say if you go 35 series it will decrease your ride quality and expose your rims ALOT more.

    Kind of a broad statement don't you think? It really depends on Load Index, Tread Pattern and overall Tire Quality.

    I can confirm that Michelin Pilot Super Sports in a 235/35/19 actually have a better Ride Quality, both handing and comfort with a lower Load Index then those crap Eagle's that come with the car.

    Not really, smaller sidewall = stiffer sidewall, if you run both tires at the recommended pressure the 35 series rubber will be harsher, also offer less protection from potholes as well as impact damage at speed. I will say EVERY tire is an improvement over our Stock Goodyear All-Seasons on the Si, have new tires waiting to go when I finish my BBS refresh project hopefully this long weekend:)

    Your wheel and tire setup looks Awesome BTW.

    I'm still gonna have to disagree with you there man. Less protection, sure you got me there. But smaller sidewall= stiffer sidewall? Again, that's too broad of a statement.

    A 235/35/19 Drag Radial Tire will have a much softer sidewall then a 235/40/18 High Mileage rated commuter tire.

    I know that's a bit of an extreme comparison but the point I'm making is Load Index means everything. A lot of people don't pay attention or even know what a Load Index is. It's the weight the tire is rated to carry. The Higher the Load Index, the stiffer the sidewall is.

    The Pilot Super Sport Tires I'm running have a relatively low Load Index. Hence, the sidewall is not very stiff. In fact, it rides BETTER and LESS stiffness then the OEM tire. Do I have as much protection as the OEM Tire? Maybe not. But my ride is not stiffer by any means. In fact, the ride is better.

    Pro-Kit installed on my Si Coupe this weekend, loving the drop and feels pretty much exactly like stock. Made sure to cut the bump stops as directed in the included instructions.

    Would I have to cut the bump stops to use the Eibach Pro's? Aren't they an important feature for ensuring the safety of suspension components on crappy roads?
