It makes sense that the springs and rods arent that beefy. They were pushing for max hp number and fuel efficiency at cheap price. Heavy springs are bad for hp and reliability, heavy rods are bad for hp and efficiency.
A warranty that changes the oem 5 year 60000 to 40% less at 3 years and 36000 miles... If that is what you call "safe". Also void if you go to the track... Road or quarter mile. So " safe" is relative...
Edit: and yes, must be their tune, which is about 240 whp 185wheel tq, which is nowhere near 300whp...

i agree completely, that is why i chose to only change out my rods and springs to save money on my budget. i had my spring failure with only 2,000 miles approx on my compressor.
my failure also occured at idle at a stop light so i was lucky to not have serious damage done when the retainer dropped.
im not sure how to upload pictures but i have some on my instagram page " @

the next thing will be your transmission when you get up around 400whp ive heard but who knows when you are way above double this cars stock power. anything may pop.
