Me too. Quite impressing for the price.

They are light for that size! I thought JR was cheap knock offs of famous Jap wheels

And is there any indication they are not cheap knock offs? As in because they are light does that mean they are well made? Genuine question incase that sounds like I'm being funny!

They always have been. Seems how many wheel manufacturers start out. JR, Bola, Rota - all made names for themselves by making cheap knock offs. Both JR & Bola are now offering very light weight forged items but I would still personally stay away from the brand.

There are enough light weight wheel choices out there from reputable manufacturers

Was looking at these myself in Bronze, but I was unsure if ET38 would fit, as ideally wanted to stay with standard ET45, interested to see what they look like on.
18x9.5 ET45 was my preferred choice.

Yeah, it is a bit low but since I always have quite a lot of camber on my cars to get even tyre wear on track I think it'll work well. The lower ET even might be neccesary to clear the struts with camber added. Dunno....

With a camber bolt, one actually increases the scrub radius, so a lower et added on top of that further increases scrub radius. Likewise, wider tyres add to the leverage on the king pin axle. Just to say such changes will affect steering (brake steer, bump steer), and probably will be markedly less pleasant away from the track where surfaces may be uneven and rutted.

Just for information for people considering this.

So is the best choice to try and keep the standard ET45 if possible, ive been hunting around for wheels but most sites you can not search by ET.
Motegi Racing do a MR145 Traklite 3 wheel 18x9.5 ET45 which is also light, but made in the USA and by the time they get to the UK they are 2.5x the price.

I know, but what to do if the rim gets to close to the shock/spring when adding camber with camber bolts. Would rather add camber at the top mount keeping more of the overall geometry intact.

But as you mention, this is for track.

I went back to the stock rims recently from my very heavy winter rims, oooh what a relief. The ONLY differences with my winter after market rims (that made quite an impact on the driving) were 7mm lower ET and a lot heavier rims. Made an impact on tramlining but also heavier steering around center. This with the same tyres (I temporarily had the CUP2C on them)
