Difference In ET Speedline Turinis To 172 Cup Turninis

[DannyD172]

Hi all,
I am to understand that if i went to speedline and bought some 16" turinis for my 172 cup (as it came on silly team dynamics) they would be a different et to what came on the car originally?
What is the difference?
Quite new to this so any help would be grateful.
Thanks
Dan

Hello Dan

I believe the 172 cup turini's are ET 37
I know the Speedline turini's are ET 35 and ET 40.
Also the Cup and Trophy turini centre caps do not fit the Speedline Turini's.
You are better off looking for a second hand set of cup turini's on here, getting them refurbed.

I thnk,Trophy offset is 45 and cup 38.5.

What are the silly team dynamiques?

I thnk,Trophy offset is 45 and cup 38.5.

correct

 

[daddycool]

is the offset positive or negative?

 

[ripp]

positive. negative offsets are quite rare

cheers, bit confused now though. given that the trophy wheels are et45 and cups are et38, i'm right in thinking then that the trophys stick further out than the cup alloys. i've read that the non-cup clios have an offset of 36. i'm told the offset gives the cup its wider track, but 36 v 38 is only 2mm further out each side and the cup track is 10mm wider each side.... i'll stop now, hopefully someone can explain

 

[ripp]

et 36? no, the non cups 172's are et 48,5 (phase 2, can't remember ph1), the cup is et 38 so 10.5 mm wider on each side.
and the trophy wheels being et 45 it means they give a narrower track than et 38 (the smaller the number- the wider the track)
of course, trophy has different wheel hubs meaning it has probably the same track as a 172 cup
on the same car, to clarify, the cup et38 wheels will give a wider track

As above really, I always remember it as, the lower the number et, the more the wheels stick out, and so on....

 

[daddycool]

cheers. i've been looking at pictures of wheel offset and i just can't grasp it for some reason. i'll just think smaller = wider, thats easier.

Exactly, so a 182 with 172 cup turinis would have a wider track than say a 182 with Trophy Turinis (and possible rubbidge if being lowered quite abit)

to better understand how the ET is measured check this:

[Fred@BTM]

ET38.5 on the 172 cup stick out further than the ET45 on the 182

Also, if you're planning to lower a Cup-Packed 182, you'll need the Turinis made for the Trophy with the higher 45 offset.

Either that or roll the rear arches.

I think I need a small lie down.
