Yes, the 17" fits front and rear. It comes standard on the Integra base model, which has the same front brakes as the A spec.
1. Yes, the external diameter matches that of the oem 18" tires
2. Any wheel+tire store. If you insist on an oem wheel you'll need to go through Honda/Acura part...
I ended up using one of the fullsize 17" oem wheels as a spare. Found that it fit perfectly under the trunk floor, and needed an M6 bolt to secure it down.
I didn't save the PN, but if you search online Honda parts stores you should be able to find it.
Thanks for confirming this!
I've gone ahead and ordered a 17" winter set.
Will also see about getting a 17" space saver spare.
I see it online as a kit, but without detailing what's included in the kit (e.g. jack, wrench, trunk mounting hardware).
I have found the 17" kit for the '22 Civic...
I have nearly new 16" Blizzaks from my previous car (215/60-16 vs 215/50-17 stock. 2.7% bigger) and would like to continue using them on the Integra (taking delivery next week).
Will 16" wheels fit the Integra base?
