Pros and Cons for adding spacers

I'm seriously considering buying some spacers (15mm in front and 25mm in rear) and I'm curious what the pros and cons are? Thank you for your help!

What's your purpose? Do you track your car? Steering might become a tad more physical but many do it and are happy with the result. I was personally looking at a similar set-up but will have a set of wheels custom made instead as I do other changes at the same time.

Not really any cons to be concerned about, even 25mm in the rear is not going to have any drastic negative effects. I have 15mm all around and didn't notice any physical difference after I installed them.

Pros: Looks so much better.

Could void warranty for suspension issues such as wheel bearings.
Easier to curb rash rims

Could possibly accelerate wear of the wheel bearings.

Also, by moving the wheels out further I'd be concerned about stones and debris being thrown up against the body work which already suffers from soft paint that is prone to chipping.

There's actually a huge con, it totally changes the suspension geometry. The preceding is on top of the additional stress on wheel bolts/studs, additional unsprung weight, and additional stress on the hub and wheel bearings.

Overall, the only reason you would really do this, is for looks. We need to understand that our factory wheel off-sets (really on any sports car worth a lick) isn't incidental. The vehicle dynamics guys spent countless hours getting the geometry right to get the best handling out of the car. Wheel spacers basically throw all that work out the window.

If anything, it makes the car handle and track better. There is no additional stress on the bolts or hardware. The car is not heavy enough to even stress these bolts in anyway. Unsprung weight is minimal compared to the benefit of the handling.
Not to mention, the car looks like crap with the wheels so far inset. The idea that the dynamics are thrown of is just hilarious. Your just talking out your ass. Maybe on a 3000+lb car it might make a difference. The car sucks ass without them. It's a trammeling nightmare, paired with those horrible Pirelli tires. Next best thing you can do is change the tires out to some Pilot Super Sports...

If they spent countless hours, it was to make a car that was practical and any idiot could drive. All cars are a platform to aftermarket companies, to make them better. Every car out there will benefit in some way from aftermarket parts, not made by the manufacturer. Hence, why we have a million race companies producing parts for cars. If everything the manufacturer did everything perfect, there would be no need to make any parts.

The only con would be to additional rocks being thrown by using a wider tire. Which has not been a problem with 13000 miles.

I like the look but on my old Ferrari, within 800 miles of adding spacers I had 2 wheel bearings go.... admittedly it could be coincidence but it did seem odd.. 32,000 miles on the original bearings and then both went noisy soon after.

Michelin pilot sport ps2 dual compound. Looking forward to putting this on.
