Looking to reduce unsprung weight on my 2007 exige, considering replacing LSS stock wheels with RS 134 Monolites 16 and 17 inch wheels. Are there any other wheels as light or lighter than the monolites out there for the exige? Appreciate any input on the matter.

In the 16x7 and 17x8 sizes, I know of nothing lighter than the Monolites. Outstanding caliper clearance as well, even with the AP Racing 4-wheel BBK. Lastly, they're easy to clean, which is the opposite of the LSS wheels.

Good list above but the offsets can vary. An additional option for light 7",8", retaining the factory diameter and offsets - Lotus Sport 5 spoke as were standard on the 240R exige 12.1lbs fronts, 17.05lbs rears. I believe that these are still available.

Thanks for the input guys, all the good info convinced me to order the monolites. Now just have to decide between silver or black to go with the lotus racing green, leaning towards black wheels.

You might want to consider two piece rotors for additional unsprung weight savings.

I have the Boe 2 piece solid rotors, they are advertised as 5lbs lighter per corner, but that‘s not what I got. I weighed them and compared to the stock, and it’s less than a pound difference, very disappointing when you pay good money for what’s supposed to be an upgrade.

The two piece are lighter not the solid. They have aluminum hat and then as rotors wear you replace just the ring. I don't even see the one piece listed anymore. How long ago did you buy them?

Sorry I misread your post maybe the five lbs is total weight savings? Anyone else do some checking on weight savings?

Need a little claireification BOE used to have I think a solid rotor as well as their two piece fixed and/or floating rotors but never a two piece solid rotor. So which do you have? If you have the one piece solid rotor it will not have the bolts attaching the rotor to the hat and there wouldn't be much weight savings. Can you verify what you have? Photo? Richard

This is a great suggestion for unsprung weight savings. Our ULTRAdisc two piece rotors have been the best option on the market since 2005. We have 100s of happy clients who have realized 10lbs of unsprung weight savings and VERY LONG life with our complete kit.

Monolites are the lightest in the 16"/17" combination. Plus the fit is also excellent.

The rotors I bought from Boe are the 2 piece with aluminum hats, you can get them in FIXED (Sorry I called it solid) and FLOATING, they are the same weight. As of Boe's website they state that the Elise/Exige HP rotors save 20 lbs, which is far from what I found.

From Boe website: Save Weight with a full set of Evora rotors saving about 11lbs of rotational mass and a full set of Elise/Exige rotors saving about 20lbs of rotating mass!

Your 2 piece rotors use aluminum hats and same size rotors as stock for the front, but a smaller rotor in the rear. That's fine if you run stock rear calipers, but not for anything else.

Ok understand you now although they call it two piece fixed and floating on their site whereas the solid were one piece. I never had the OEM rotors to compare to as the car came with BWR two piece fixed same as BOE's. I've begun changing my drilled rotors for slotted after seeing micro fissures around some of the holes after refacing. Strange that there would be that much weight discrepancy. Richard

From what I understand, the TR Motorosports F1 wheels are lighter than the monolites, and from what I can tell, they are the lightest 16 & 17 set ever available, but they are discontinued. I have a set that I would be willing to part with if the price was right.
For 16/17 setup, the lightest are not RAC Monolites.

RAC Monolites are 11.5lbs front & 13.4 lbs rear if you're looking for 16x7.0" and 17x8.0" wheels respectively.

However, for stock sizes, the lightest is TRMotorsport F1 from TireRack. It's 10.5lbs front, & 12.0lbs rear.




Work wheels don't make sizes for the Lotus. You see them mainly on Honda/Acuras, and other "import rice rockets."

No, they're not. I was very specific in saying that in the 16x7 and 17x8 sizes, I know of nothing lighter than the Monolites.
