now that i see my message went thru...im computer challenged watching me trying to figure out the internet is like watching some kid in the special olymp..... i better not go there.im new to the z world years ago i had a 928 porsche which was allot of fun but i sold it after a year, two years ago a customer backed out of a deal for an nsx and four years ago i let a pantera get away..last year i was working on a house and told the lady if she ever wanted to sell her 1982 280zx stick call me.. she did ..i bought.. i like...,39000 miles always garaged original owner.., im having allot of fun driving it..it handles fantastic especaily in some areas where there is no one around i drive it quite hard...the tires have allot of tread but one is 19 years old the other 3 are 11 years old. i met a z owner who suggesting i go with 225 60 14s instead of my 205 70 14s more rubber on the road.. problem is bfgs are it ..and nobody seems to like them all that much, bottom line i've heard so much about the 240 zs racing ability, is a STOCK 240 vs a280zx FORGETTING ALL THE BELLS AND WHISTLES that much better handling and speed wise ..and is the 280 limited to the point where tire size and brand are academic..when i had my 928 there were other porsche owners who looked down on the 928, v8 and all, but there were some guys, one out in arizona as i recall who did some amazing things to the 928 and handed porscha owners there lunch..the z crowd doesn't seem to have that attitude regarding different modles..
