Since I had the R888's put on the Cup wheels I thought I would add that real-world weight as well. Interesting how the Cup front wheel doesn't weigh any more than the LSS front wheel, even though it's .5" wider.

Front:
240 Cup wheel / ADVAN A005 - 16 x 7 190/580/16 = 27.3 lbs
LSS wheel / TOYO R888 - 16 x 6.5 195/50/16 = 32.8 lbs
240 Cup wheel / TOYO R888 - 16 x 7 195/50/16 = 32.8 lbs
XXR 527 / ADVAN AD08R - 17 x 8.25 215/40/17 = 40.8 lbs

Rear:
240 Cup wheel / ADVAN A005 - 17 x 8 230/625/17 = 33.7 lbs
LSS wheel / TOYO R888 - 17 x 7.5 235/40/17 = 39.5 lbs
240 Cup wheel / TOYO R888 - 17 x 8 235/40/17 = 40.6 lbs
XXR 527 / ADVAN AD08R - 17 x 8.25 235/40/17 = 44.5

That's honestly not that big of a difference on the rear. Of course the front has a bigger delta because of the 1" bigger wheel and wider tire.
Thanks for the additional data points!

I feel like the XXR's are kinda like RPF1's in that sense --- they tend to look good on any car.

Thinking of K-swapping? Here's an idea of the cost involved.

I agree with that for the most part, but was just having a conversation with a guy on another board yesterday about the RPF1. I have an Acura TL for my daily, and for his TL it was suggested that he get RPF1's. To me, they don't fit the nature of the car at all, but on just about any sports car they are fantastic.

Sorry to wake the thread up but I have two questions.
if these wheels fit your exige would they fit an Elise ?
Are you running any spacers to clear anything ?

You'll most likely need spacers as my latest searches do not yield the correct offsets in the 527's.

The Elise and Exige are exact with regards to room in the fender/quarter.

No spacers needed.

I have some updates, will post soon .

IIRC, the front clam is wider on the Exige. Unfortunately, the rear clam is not.

So even with the +0 offsets that are currently available the concave rim clears the calipers? NM... Just noticed both Front and back are 17/8.25 +25

I've always been told the Exige has wider front guards also. I'm tempted to run 17s on the front of mine also but worried the 17x8.25s will be to wide, I know they fit the Exige front but only just

I know the front comes down wider, and the rear does as well, but at the very top where it would rub, I believe them both to be the same. But even if they are different, it doesn't matter, you could fit my front combo for sure, there is plenty of room. The Secant vehicles run a bigger tire than I do in the front.

My front specs are 17x8.25 +25 w/215/40/17

The reason it fits well is because the 215 is a bit stretched on the 8.25. This makes the OD (24.5") actually shorter, and the stretch makes the transition easier. The pic below is with just -1.5 in the front, not nearly the -2.5 that is normally suggested.

So, that's no work at all. You want to talk work?

How about 17 x 9.75 +25 in the rear with 255/40/17? Stay tuned...

OK, so I wanted to update this thread with what's been going on for those that might want to have this combo in the future. First, the numbers.

Front: 17x8.25 +25 XXR 527 with 215/40 = 40.8
Rear: 17x8.25 +25 XXR 527 with 235/40 = 44.1
Rear: 17x9.75 +25 XXR 527 with 235/40 = 45.4
Rear: 17x9.75 +25 XXR 527 with 255/40 = 47.4

For reference:
Front 16x7 Cup 240R with 195/50 R888 = 34
Rear 17x8 Cup 240R with 235/40 R888 = 41

The Advan AD08R runs wide for sure, this is a 255/40 on the XXR 9.75" wheel.





Fitted to the car with a .75" drop and -1.5 they poke a bit, but with some fiddling they could certainly work.



But seeing how little they stretched, I figured I'd try my 235 on the 9.75" wheel, just to see what it looked like. I was wanting something more stretched like the front anyway, not a crazy stretch, but more than the rear had, and this is the result.



Looks more stretched in pix than in real life, and is a TINY bit more stretched than the front 215/40 on the 8.25" wheel. With a little bit more camber, and a bit more drop when my suspension comes in, this combo will be an easy fit with almost no work at all.

This is a little photochop I did showing the difference between the 8.25" wheel and 235 on the left vs the 9.75" wheel and same 235 on the right. Again, in pix it appears more stretched than it is, in real life it looks quite nice.



My final thoughts are that there is no way I could go back to the 8.25" wheel in the back, the 9.75" looks MUCH better, and has a much nicer concave to it, especially compared to the front. With regards to the tire, the 235 is absolutely fine (and before you call foul, remember that the Singer Porsche that you drool over every day has MORE stretch than this combo has), but the 245/40 might just be the perfect tire.

We will see .

imho, 8.25 looks better to me. I'd put slightly wider tire up front and space it a bit to match the rear .

I think a lot of the older guys (like us) will probably like the 8.25 because the 235 bulges a bit on it. It's also a Lotus thing to bulge, with a lot of guys running the stock wheels with 245's on them, and the most popular tires running wide, so everyone is used to seeing bulge instead of stretch.

However, for me, I like a slight stretch, or square, so the 235 on the 8.25 just won't work. It also has the same concave as the front, which makes the rear look, for lack of a better word, weak. The 9.75 is definitely the right wheel for me, just have to find the right tire. The 235 is EASY, but not perfect.

As far as putting a wider tire on the front, it simply won't work. This tire is stretched a bit, and has an OD that's 1" taller than stock. It also requires -2 camber. If you were to put a wider tire on this wheel it'd rub on the lip, and on the liner, so 215 it is.

Having said that, I'm looking into a rare tire to match the rear to the front a bit better, so I'll update the thread when I get it .

If you decide to get rid of those lotus sport wheels, let me know.

Are you running a hub centric ring / spacer? I looked up XXRs and the bore size is pretty big. (I don't know the correct size, though.)

I will almost certainly be selling the 240R wheels, just not quite ready yet.

Yes, hubcentric spacers, I would never run open bore, they must fit perfectly.

Pulled all the shims, and with the 20mm drop I have, the tires tuck nicely. We'll see how it looks with the new tires, but for now, looks pretty fantastic IMO.
