i avoid highways most of the time with 4.30’s and a 28 tire.
yes to external cooler( imo a must)
it sees the occasional 20 or 30 mile street jaunt, that is pretty much it. I have driven it home from the track before on the highway (25-30 miles) from US131
too much stuff on the car that replacements aren’t available cruising at 9 on a Fri night. I stay within a circle of how much hurt I put on my wallet if something were to break and I had to call a tow truck. Calling it being old and wise..lol
something as simple as a flat with a spool and drag radials can turn into ruining an otherwise nice night
