Going with 18s BUT

[Bill68fbrd]

I am going with 18" (18x8 front 18x9.5 rear Budnic gasser D) on my 68 bird but would like to know others that have 18" with similar set up what they drive-cruise like:drive:
Car has Global west "pro-tour" package (Tubular upper-lower, coil overs, "deldelum bushings, QA1 front & rear, subfraim connectors, new springs etc.willwood disk F&R) G-West reccommend 17" and I will get a set for racing but want 18s for "every day" use. I want to know what they will drive like with solid mounts etc.:3gears:

Bill :santa3:

Mine drove fine and I had solid mounts.. I don't think they will ride much worse than 17's. The real downside is weight and rotating mass. Generally 18's are nice to fit in huge brakes but 17's will perform better and maybe ride just a tiny bit more due to a (generally) taller sidewall.

They do look cool though :)

depending on the roads you have around you it might be abit harsh...comfort is subjective.

Tire pressure will also play a big part in how harsh the car rides, especialy over rough roads as Vince noted. If you run pressures on the higher side, it will be much rougher, as opposed to the lower side. Some guys run stuff like 36/42 front/rear, and it's gotta be pretty rough. When I got my 18" ROH and Kumho's mounted, the guy filled the tires to 45-50psi. It felt like I was riding around in a dump truck. I changed the pressure to 28psi rear and 32psi front and it made the ride much, much better, not to mention handle better. Hardly any difference from the 17s to the 18s, as well. This is on a 4th gen, though.

Thanks guys everyone around here (NZ) thinks 18s on our roads would make your fillings fall out but I like the "look". The difference from what you say is not that much thats what I wanted to here. The only other "Pro-tour"type car I know of is a 67 mustang.
If i ever get mine done it will turn heads especially when I pass them.

I love the way my car rides even with stock factory shocks and stock factory springs. Well front are cut and rear are de-arched but still rides decent even on Michigan crappy roads. I can easily ride for 9 hours with no comfort problems. Make sure your SEATS are comfortable. I have 4th gen and never uncomfortable.

It's not impossible to find 40 series tires for 18" wheels these days. If you have room --or can make room--for the extra diameter, then you can have the best of both worlds.
