CAD simulation done. Est. weight 15x7 et45 @ 3.8kg (8.36 lbs). We'll be forging and machining a few samples for real world testing soon.

Once we have test results confirming the production ability of the manufacturing plant we'll roll right into production of 15x7, 15x8, 15x9 wheels. 17" and 18" race wheels will follow after.

did you consider barrel size of the rim? you know, for the guys that run type r, or nsx calipers?

Xian

If you can actually get these to market, you'll sell a ton (obviously).

ITR/NSX brakes with 11" rotors are very easy to clear on 15" wheels. It's the larger disc setups that might have clearance issues...

I like it

FlewByU352

I approve but the offset is boner as ****!

Yep agree on the offset. Im not a 5 lug guy but you would be smart to cater to that market to be honest. enough 4-100 wheels In the world

jdm_AE86

Not true. There are many 15 wheels that dont clear 11 inch brakes. Mostly depends on offset and sometimes the design of the face.

15x8 +35 4x100 would be nice.

What he said!

I like! Also, would be interested in five lug!

Looks good to me I'd rock them

^^^ this. some guys have had issues with running 15" rpf1's with typeR calipers and 11" rotors. the inside of the barrel hits the calipers.

redGSRguy

Where is the plant?

exgr

RPF1 is known to have some what poor caliper clearance. notice our spokes are very straight and we didn't really care to design for a lip. we prioritize strength and lightweight over looks. we'll probably simulate a split spoke design to compare...

planet earth. we've decided to use earthling technology for now. earthling are not ready for advanced martian technology yet.

Xian

Hey look, Frank made it to post #15 in the thread before turning back into an asshat...

jdm_AE86

You are right about that. The wheel does look to have a good design for caliper clearance. The offset on the other hand might come into effect for more aggressive brake setups.

exgr

art of trolling son. humph.

ps, what part of using earthling technology is being an asshat anyway?

90_EX_Civic

well now... question goes, how much?

exgr

can't tell you guys until i know what my cost is... still working out machine time, forge tooling cost, painting and packaging... etc. it will not be cheap that's for sure. think Volk Racing TE37 level if not more. i'm using a special alloy this isn't the average stuff.

Same here! 15x8's are getting more and more popular, so much so I'm not even sure it's worth making a 15x7. Or maybe there are some classes where you're still limited to a 7" wheel?

RPF1's have horrible clearance. I didn't know this and assumed they were like any other average wheel. Bought a set, put my tires on then went to mount them the night before an event only to find out they wouldn't clear my new ITR brake setup. 20mm spacer + an angle grinder made 'em BARELY fit.

I don't mean to be discouraging as I think a larger variety of good, strong, lightweight wheels is always a good thing. But seems like entering the market at that price point may be difficult. If you can get the weight below that of a Volk of the same size then you'll have a leg up in that regard. Otherwise you're going to be fighting an uphill battle competing with them since so many people (I assume) would opt for the Volk if the price is the same simply because they have history, plus there's the "baller status" associated w/ Volks. I'm exited to see what happens though, and wish you luck!

I think this is a legitimate question. What country will the wheels be made? Being made in China will extremely devalue the wheels.

This is great news. I've been looking for a 15x8, 4x100 in a +40-45 offset, but I can't seem to find any. Do you have an estimate on how much the 15x8 will weigh?

exgr

15x8 with a 45 offset will probably hit the front knuckle and it will also hit the rear trailing arm. assuming you're talking about EG fitment. if this prototype passes all 500kg 4x100 tests then a 15x8 rim should be about 10 lbs. if we ended having to strength certain areas then it might weight 0.5 lbs (maybe up to 1 lbs) more...

the origin of the raw materials is a better question to ask than where the forging is done. the type of plant and their experience (our guys are experienced forging aerospace components). there are good forging presses (6000T to 30,000T) in Russia, China, Taiwan, Belgim, Japan, USA. where we source is obviously a inside trade secret. machining workshop is also carefully chosen and evaluated.

we (try to) use the best possible while balancing it with price point that is acceptable.

for more 5x114.3 options!

Silky Smooth

That sounds like a well informed response. Thanks for the heads up about the new product.

I don't have an EG. I have McPherson struts in the front and a live axle in the rear. The inboard side of the wheel is not even close to the suspension. A +35, 8" wheel will have a slight poke in the front and that is a look I'm trying hard to avoid. I'll figure it out. I'm just considering options right now.

By your response, it sounds like you might make the 15x8 wheel in a different offset. What offsets do you expect to offer for a 15x8 4x100 wheel?
