well the theory with a 6th gen is that if it could fit, they would have released it for the f23. their is still a tight fit for 6th gen w/h22s also in the strut tower and firewall area just like 5th gens although their may be room. yeah JRSC seem to be overrated in general from what i hear. i have no personal experience with one or know anyone with one. on po.com we did talk a guy from nashua out of a JRSC for his lude.
