Does one brand tend to be quieter or built better?
Leaning toward FRPP and it goes for like $180 where i can find it in stock right now?
Street car (summer only) 4-5K miles and like 2 trips to the drag strip a summer as well
Also any synthetic 75/90 gear oil fine or 75/140? Like royal purple?
Also royal purple and red line say they have the friction modifier in them, do I still need a small bottle?
Thanks,
