Thats my only concearn it's like I love the idea of the z but no practicality ... But the ringland concearns me then people saying stage one I'm not going to void the warranty, so I'm worried about that reliability but I don't know out of the millions plus the sti got more reliable ratings and "recommended" by consumer reports where as the 370z got worse reliability and not recommended. Justwant to know its a good ill Truro listen to you
ringland issues are rare on the newer models. 2008 was a really bad batch. i've tracked my car, i've seen wrxes and stis on the track far longer than i have, and they've had no problems. it's not perfect and it's not a guarantee, but the ringland issue has definitely died down in latter model years.
or I guess should I ask them to install it if they can without cleaning I was going to take it to a car wash where I see lamborghini and ferrari and nismos and skyline gt'rs being hand wash then taken back
