The amuse R1 car runs ce28n 17x9 wheels all the way around. I'm guessing they use the same tire sizes too... obviously a quick track car? what's the idea behind this?

 

They have more clearance for one thing to be able to run the 17X9 on the front. They also have a different suspension and it is a track car only. They don't have to compromise for street driving. What works real well on the track can be a pain to drive on the street.

 

handling is handling... it's made to go around corners... fast. would this not transfer over to the street? just wondering.

 

Most people talk about the non staggered setup without looking at the big picture or understanding why some do it and others don't. Amuse isn't the only company that runs the same sized wheel/tire all around. You can run a 17x9" all around with stock suspension, BUT, for optimal handling, you'll want to run more camber in the rear than the front, which is what you usually don't do when setting up a car.

Basically, the best way to get a car to stick is to get a very very wide tire at all ends. Thats part of the reason they run a 17x9" with a 255/40/17 up front. They run the same size in the rear for balance, and because, an N/A S2000 isn't going to need a whole bunch of traction in the back vs. a 400hp drift car. Rolling the front fenders with a 17x9" with a +6X offset usually isn't required, even if very low. The Volk CE28N and Racing Hart CP-035 is available in a +63, the Volk TE37 in a +65. The reason why the Amuse R1 is flared out so much is because they are running a 17x9" +40 to clear the bbk. The run the same offset in the rear to proportionately widen the track as they did up front, and because they can swap all four wheels front to back/side to side to make tire wear a little more bearable.

Also, yes, the Amuse car would be considered a race car, but in the "Touge Challenges" they are required to run street tires, and the Gunma Cycle Center is more like a street than a flat race track. But, their suspension setting is very wild for the street.

Amuse/Bilstein Hi Tech dampers (12k/14k)
stock roll bars (I believe).
camber is between -3* to -4* up front, and around -4.5* in the back.

That wouldn't be very street friendly, but the Street Version runs a lot less camber, no BBK, so they can run a +63 all around with 245/255 Advan Neova's and the street Hi Tech dampers which are 7K/8K.

The S2000 isn't the first chassis I've seen the non staggered setup applied to. A guy by the name of Damon Delahuerta (sp?) who I met at ITR Expo 5 had a full race prepped FD RX-7. He ran Kinesis wheels same size/offset all around with a 285 series tire. Part of his reasoning behind it was tire wear.

I hope some of this points you in the right direction. Feel free to PM me if you want to discuss this further.

PS: I'm not preaching this as the only way or the right way to do things, just giving my 2 cents.

 

the te37 isn't available in 65+ for 17x9 last time i checked. it is for the le37t black/polished lip...am i missing something here?

 

Take a look in HyperRev Vol. 74 I believe (the second S2000 one). They have a few owners running this size, and list it in the back. Bulletproof can also get it for you over here. I don't think it's listed on the Rays/Volk site.
