it really is not offset related it is just whel design and in order to achieve the "concave look of the first pics .... you would have to examine what is more important brakes or visual appeal ... the reason the second car pics are concave on the rear and convex in the front is to clear the Brembo's

Those 19s on the back definitely look awesome with the concave look!!!

 

when you consider the wheel design you can have a large mounting pad area on the back side of the wheel to achieve a low offset without the "deep lip" or "concave" look or the design can have a small mounting pad area and have the "deep lip" , "concave" look and be the same offset so, offset is not the determining facture it is wheel design ... consider Porsche wheels .... the OE have a flush face design and many of the aftermarket wheels have a huge lip and the same width and offset as the OE wheel.

Here are a couple of wheels with the same offset and width
both wheels are 18x9 ET35

 

Umm... what year silvia is that?? Can I make one like that from a 240SX here in the US?? Anyone know what body kit...etc?

 

Victor,

You may want to check out Skidazzle's forthcoming setup.

I think he is going for this type of look, but with the GT-C's

Front = GT-C 19x8.5 Face1 (outward spoke design) +27
Rear = GT-C 19x9.5 Face2 (inward spoke design) +24

Enjoy

 

luke is right about the rim design vs. offset for that look.

the offset is not a factor at all. its more the design of the rim, and how shallow of a mounting pad the manufacturer uses to get that sunken spoke look.

volk got this look on the GT-C by putting 2 flavors out (face1 and face2). other makers achieve this spoke difference by specifying front and rear sizes seperately on each wheel type.

offset is the distance between the center of the rim, and the mounting surface. this is why my +24 rears have a waaaaay thinner mounting pad, vs. my front +27. the difference is was over an inch, while the offset is only different by 3mm.

this is because when the sunk in the rear spokes, they needed to have less mounting pad thickness... if not, the offset would have been somewhere near -5.

another note is this look is almost exclusively on RWD cars only. like the M series BMWs and the AMG MBs.

HTH,

PS... if all of this conceptual explaination does not help you victor, i can take more pics to show you the "trick" to get this look.

 

Achieve this concave look in the back? I ordered 19X8.5s and 19X9.5s. I hope it'll have the same look as the picture on the Ray's site: www.rayswheels.co.jp

Please explain and thanks!!!
