Before you move forward just read about Positive Scrub Radius, to make sure you understand the changes in your car handling.
By adding 15mm to the front, the car will have an added 15mm of Positive Scrub Radius. This will make the steering much heavier, may cause some side pulling when you break, and wear your tires quicker. Since the car is rear wheel drive and uses double wishbone suspensions design, a 10mm increase in the rear may be a positive addition, and help to counter the front positive scrub, but the front may be a problem. If you do not plan to track the car or drive aggressively , this may not be an issue, but if you do , then consider this issue. In any case, get an advise from an expert so you can assess this.

You use spacers for show (I do too).
If you want to GO (track the car), remove the spacers, go back to the stock setup and track. You're far better off including getting the most out of the steering and suspension geometries designed into the car.
In other words - Don't track with spacers, there is no upside here, only downside.

I very much agree. I mentioned this in another thread.

Most people (say more than 1/2) that make these changes also start to mess with the geometry more generally; aftermarket wheels without spacers will often push the offset parameters as well. As soon as you consider lowering, that also adjusts this calculation, along with camber etc. Most people even on the track won't notice spacers affecting their track time. I think it's akin to swapping lugs to titanium for lower unsprung weight and expecting noticeable changes. Porsche even offers a 5mm spacers as an option in their builds.
