Well I would "guess" they are most likely the same dimensions, but we can't be 100% sure unless you test fit one..

the X-Pac wheels have different spoke designs so someone will have to test fit to see.

The problem on the 2 IS 18x8 split 5 spoke is not the spokes.. they clear the IS-F caliper just fine..

its the inner part of the wheel barrel... it looks like it has an approx extra 1/4" lip that carries accross the inner surface..

If the wheel didn't have that lip.. it would clear .. but its part of the design..

Red circle is where the IS-F Front caliper touched the wheel.

Rays website have lists of sizes and offsets for different wheels, with the offsets mainly categorized in Offset A, B or C group. The below is an example of a footnote usually accompanying these wheel size charts.

･The OFFSET A in the size table denotes models matching big calipers of SKYLINE (including the BREMBO caliper of V35), SILVIA, FAIRLADY Z (Z33), CELSIOR, SUPRA, RX-7, LANCER EVO and IMPREZA (BREMBO calipers).
･The OFFSET B in the size table denotes models matching big calipers of FAIRLADY Z (Z32), RX-7 and IMPREZA (BREMBO calipers).

My question is this:
1) If I choose Offset A sizes, will I definitely clear the IS-F BBKs, both front and rear?
2) What about Offset B sizes?
3) Offset C = no go?

I'm about to pull the trigger on purchasing a set of 18 inch Volk Racing GTMs with Offset B sizes for my IS250RWD. Front: 18x8J +35et, and Rear: 18x9J +41et. Just wanted to make sure that the wheels will clear my future upgrade

I have Volk RE30s 18x8 and 18x8.5 with 44 and 52 offset and they clear the IS-F brakes with no clearance issues at all. Probably a good 10 mm clearance all the way around and also the face of the brakes.

According to RAYS website, the footnote in RE30's size chart states the following:
･The ■ marks in the size table match BREMBO caliper of IMPREZA.

So since the GTMs states that for both Offset A and B will match big calipers of IMPREZA (BREMBO calipers), I can safely assume that these GTM offsets/sizes will be able to clear the IS-F brakes?

Would these fit on a 250?

So some more quick fact updates..

• The IS-F Wheels will fit an IS250.
• The IS-F Wheels can & may fit an IS350 with a spacer
• The IS-F wheels are directional. (RF, LF, RR, LR)
• The IS-F can have proper designed 18" Wheels installed for a winter set up.
• The Front 18x8 Lexus ISP Mode wheels for the 2IS, will fit over the IS-F brakes on all four corners.
• The IS-F Braking system will NOT just bolt right up to an IS250 or IS350. (Custom fabricating required)
• The Front IS350 Rotors are directional. L & R
• The Front & Rear IS-F Rotors are NOT directional.

I will add or change more to this if need be...
