hey guys/gals i am looking for some opinions on different brands of rings. I recently rebuilt a gsr and for the first 8k it was perfect and ran flawless. A week ago i noticed smoke and a compression and leakdown test led me to find my #4 cylinder rings collapsed. all the others are perfect still. I have a set of rock rings right now the machine shop recommended because they break in easy and all that. Should i run them again or should i get something new? i will be re-ringing just the one bad cylinder. they will be going in a boosted gsr.
thanks for the input

total seal is the best brand name out there... but you WILL pay for them
