I will have to order wheels soon and was wondering what the consensus was for what the best 16" wheel option is. The OZ's are the lightest from the Tire Rack (14.5 lbs) but there are far cheaper options starting at half a pound lighter. However I assume there are many other wheels out there that they don't carry. What's good?

Please include the brand, model, weight, offset and price. Thanks!

Check out these. I have them on my car for my winter set, but may get something else so I can use these for summer. I saw a listing that these are only 13.5 lbs!

They look nice . Weight is a little hard to determine however. Rota lists no weight on their page and I’ve seen quotes from 13.9 to 16 lbs for the 16x7. Do you know the actual weight of these wheels?

 

[Firesail]

The listed shipping weight for the wheels in boxes was 60 lbs. I would believe they are about 14 lbs each. I never did put them on a scale to check.

Thanks! Sounds good, I’ll likely order myself up a set. I’ve been having trouble finding the 4x108 pattern besides your one link. Are they rare or are the 4x100’s double-drilled to 4x108? I’d really rather have silver wheels to go with my blue Fiesta.

They seem to be like hen's teeth. Mine are not double drilled.

hard to find but worth it in the end

Damn, just before ordering them I checked their offset and discovered it’s 40mm vs the 47.5 mm of the stock wheels. Maximum offset delta in SCCA is 6mm so the Rotas are illegal. Back to the drawing board!

Too bad!:thumbsdown: They fit the FiST like a glove!

There are not tons of choices...Team Dynamics seem to be a good option, a bit more expensive than the Sparcos that most people are going with. There is a place on EBAY that has them out in California. Would love some Enkei RPF1's...but no joy there. I also talked to the guys at 15 52 and they don't have a 16 that would fit our car either. I think there may be some other Rotas that are an option, but not positive about that.

 

[stuntdoogie]

Rota 15" RB's are the obly other rotas that fit.

Most of the other options like the Sparcos are too heavy. The OZ Ultraleggera is the best legal option I've found do far but they are $227 each plus they are the same wheels I had on my Solstice and I'd like something different if possible. I might see if it's possible to machine 2mm of material off the mounting face of the Rotas but I'm not holding my breath.

Fyi Alan, I went with the Sparcos, and mounted with both the Rivals and the Z2s, they weigh the same as the OEM. Almost exactly the same across all three. I was hoping for some reduction, but not with these heavy performance tires.

 

[WestcoastST]

What size wheels and tires did you fit the BFG rivals on? 16" or 17" tires?

 

[Cligedy]

Sorry, the 16x7. I should have included that. The Z2s are 225/45 and the Rivals are 225/50

 

[AlanBDahl]

How do you think the 225/45s work vs the 225/50s that others are selecting? I'm planning on the 225/45s too unless I decide to go with 17s instead.

Test & tune this weekend, should have some feedback then. This will be a steep learning curve for me. I've never driven a Fwd car, I'm running staggered tire compounds and sizes, and I don't even have much of a baseline for starting pressures.

 

[Cligedy]

Test-n-tune was yesterday. Due to a big turnout, I didn't get as many runs as I had hoped. I was able to work mostly with front tire pressures, settling on 42lbs with both the Rivals and the Z2s. I may try to bring the Rivals down another pound or two, as there was minimal scuffing at the edges.

I was running 45lbs in the rear and rotation was great. There were no really tight turns, but on a decreasing radius sweeper I kept clipping the inside cone. A tighter course may benefit from higher rear pressures.

It has been a few years since I competed, and I was surprised by how rusty I was. Nevertheless, the car was really good. As I suspected, fast transitions are the big challenge. This car leans a LOT. With the Rivals up front , there was a lot of rubbing when the car leans. It's not bad enough for me to not use the tires up front, but enough that I wouldn't recommend them without reservation.

After all was said and done, I was the fastest GS car, 14th time overall, and 4th pax out of 89 drivers. There was another FiST driver on oem tires who laid down his fastest time by accidentally leaving the traction control on. He was about a second behind me on the 36-40 second course.

By the way, a true limited slip would go a long way in this car, lots of wheel spin in the turns.

 

[Slowclimb]

Good information there...thanks. I was planning on starting with a min of 45 lbs in front and rear and reducing front until I get the rotation I like. Controlling wheel spin is going to be a challenge for sure.

 

[RodMoe]

SO the BFG's leaned more than the DZll's ? or the car leaned a lot in general ?
