Have the option to pick up a set of 360 Challenge wheels very reasonably. Should I do so and put them on the 360 Modena ?

[archiegibbs]

They won't look out of place on a Modena as many already have them. Look like they are a bit fiddly to keep clean though.

I think the CS wheels look great !!!!

Very tempted. Will probably make a final decision on Monday or Tuesday.

The CS wheels are very nice but they are weak weak, Scott.

They bend easily! A friend bent one on his CS w/in a few weeks of owning the car due to our bad NorCal roads.

If you have bad roads there be careful.

Thanks for the insight. Potholes are a major issue. Have decided to pass.

Probabaly a good move.

You get a great deal on all four, damage one, and then that one replacement will cost more than the other 4 bought on special!

Very true

Front rims go about $2,500.00 each; rears are about $2,800.00 each!

Ouch!

Major ouch. I can get a set over here for GBP 1800.

Wow if that's for a set of 4 that's a killer deal!

Then again if one gets damaged you pay a steep price for a replacement!

Its worth adding to this thread for anyone reading/considering these wheels is that there are 2 different types alloys available, both for different purposes, either road or pure racing.

There are the 18" 360 Challenge wheels which should have a BBS logo in red on them, these are superlight and where made for racing. They are generally usuitable for road usage as they are made from a very soft metal but greatly reduce unsprung weight thus improving handling, braking and acceleration considerably.

Then there are the 19" Challenge 'Style' wheels which don't have a BBS logo printed on them and aren't superlight weight. These where standard fitment on the Challenge Stradale and optional on the F430. While these wheels are forged (and still from BBS) they are actually rather heavy in comparison to the items made exclusively for circuit racing as they where designed to handle pot holes and bumps with more resistance the bending (hence they weigh more). These are ofcourse much harder than the pure racing wheels but aren't as super racing focused when it comes to unsprung weight.

Its worth noting that some people still run BBS 18" wheels on their road cars but they are taking a chance as they are very easy to bend.

Put the CS rims on, stood back, smiled and said "dam that car's hot!" Jumped in it for a ride and noticed a huge difference... but it wasn't necessarily good... the ride was rough, the car tracked a little, and the top started making some rattling noises!
But man, in my opinion, the car looks 10 times better. Even the GF thinks so. Less roll in the corners too. I believe I can attribute the rougher ride to the lower profile tires. I'd like to put some on w/ a little taller side wall to make the ride a little less bumpy... but not sure they will fit correctly... anyone know of the fitment I could use to solve my bumpy dilemma?

[Gcalo]

I would have the rims checked for "trueness".

There is no way they would cause any "wobbling" unless you have a rim out of round or you have a tire with bad cords, etc.

I'd have that checked ASAP as that is very odd, Levi.

You have few tire choices in a higher 19" profile that would properly fit the 360.

They do look very, very nice though.

Sounds like there is either a flat spot in the alloy wheel themselves (they can get damaged, did you buy them second hand?). If they spin 'true' on a balancing machine check the weights are balanced too.

Once you've proven the wheels and tires are properly balanced and not damaged the next step is to verify your alignment. If your wheel geometry causes the wheels to point in the wrong directions/angles the car won't drive very well either. I've driven some stock 360's that have the same characteristics and its either due to wheel balancing/damaged wheels, geometry or bushes/balljoints.

I don't think I was clear enough.... the car rides really smooth on smooth surfaces, but takes any bumps in the road badly... thats Nor-cal for ya.... kinda like my Viper did. Do you know the size (#'s) tires I could use w/the higher profile? Thanks! Levi

[Gcalo]

If they are 19" rims you will get a slightly harder ride.

With 19" tires you are now running on 35 series tires which is a shorter sidewall from the OEM 18" 45/40 series.

Really not much in way of choices for tire sizes. You have to stay w/in the OEM parameters or you'll throw off speedo and gearing.

What are your tire sizes now?
