I've had a 99 miata now for about 17 months(wifes car)regular mx-5 with only upgrades so far are a set of goodyear F1 tires(195-50-15's)Their great!Had to have me one after that so I came across an 04 new with 100 miles a had to have it they made me such a great deal.When I get somev pics small enough to fit I will post them.On both my cars when I got them home I changed whatever kind of oil that was in them and put in Mobil 1 10w-30 (full syn)and noticed better preformance from both.Been running it in 99 for about a year.Anyone else notice this?
