3.3TT Light wheels and two piece rotors upgrade.

[Ohiocruiser]

Finally, got a time and a weather to install my upgrades. Pics are coming shortly. For the wheels i went with 18x8 enkei TFR, wich are 19 lbs each. Also installed front and rear two piece girodisc rotors. For anyone who is interested the front stock rotor is 25lbs vs girodisc 21.5 lbs. The stock rear rotor is 20lbs vs girodisc 14.6 lbs. The total rotational mass savings are little over 51lbs. I honestly expected better weight savings, but still are happy with what i got. And also you can lighten your car 31.5 lbs removing spare tire, wich i also did

So what made you go with Girodisc rotors? Was it just the weight savings or something else?

I am going to be looking at replacing my stock rotors and pads this summer due to the recurring vibration/deposit issue.

Yes. Wheight savings was the main idea. Bracking does feel improved, but it has more to do with new ceramic pads and lighter wheels most likely.

Wheels will have greater impact on rotational mass since you reduced the diameter (bringing weight closer to center) and reduced the weight quite a bit. The rotor will not make a big difference in rotational mass since you removed material close to rotational center but still you removed unsprung weight which is also great for driving dynamics.

What is your goal with these modification? I believe those are great mods that actually do something vs just for the look but I believe the Stinger look better with 19" wheels (some can be had light as weel but maybe not as light as yours). Also I see that you used tires that are quite a downgrade performance vs the Michelin from a overall summer performance stand point.

Sorry, i guess i dropped rotational wheight and unsprung weight into one bucket. I do agree on 19s or even 20s looking better on stinger and still being light. Just didn't want to compromise ride quality, which i really like now. Cleveland roads are not the greatest. And i know it is a "wrong" tire for this package. But driving 40k miles a year, i just couldn't bring myself into buying performance summer tires. Need something that lasts.

Sounds like you thought this out thoroughly and balanced your wants and needs.

Those front wheels are a snug fit on the calipers! I recognize the look, as my front "summer" wheels have the spokes very close to the calipers. Your barrels appear to be a lot closer than mine, though (an 18" wheel would do that). Fitting anything between them to clean the barrels and caliper's backside will be challenging. I can just barely insert my long fingers in there with a cotton T-shirt sleeve rag over them.

I noticed that too. Whith thin spokes calipers look bigger. And to clean them, the wheel will have to be removed. The barrel sits 1/4 of an inch at most to the caliper.

That's even closer than I thought. Wow! I can dangle that long-sleeve T-shirt rag down and pull it across the caliper face with an up and down sawing motion, and then get the inside edge of it the same way; I bet that you could tease a rag across the outside (barrel-facing edge) of the caliper and "saw" it up and down and keep the bulk of the caliper clean; then when you have the wheel off, do a "deep cleaning".

you definitely can call it a tight fit. I might add 5mm spacers later. Not because of any fitment concerns, but make it more flash with fenders.

That's about the same space between spokes and caliper face that I have. But your barrel clearance is crazy close.
