Purchased these for my 2014 Toyota Scion FR-S,and I couldn't be more pleased.I am using these 25mm spacers for the rear,I also purchased these same spacers in 20mm for the front.They install easily,fit perfectly,and exhibit no problems when driving.These spacers bring the stock wheels and tires right to the edge for a more aggressive look,and better handling.These are made specifically for the Scion FR-S,and fit with no modifications at all.I would highly recommend these spacers,as well as all Eibach products.
