I recently acquired a well-tuned 1989 Prelude (not the AWS model) that is quite fun to drive. Fuel-economy is atrocious for a 4-banger, however; and I suspect the tiny 175/60R13 tires are to blame -- as the engine is whining at near 4000rpm going 75mph. 1st gear is also a joke: if a snail breaths on the rear bumper, the car is moving fast enough to shift into 2nd.
Could someone post the bolt-pattern specs (four bolts), and largest diameter tire I can reasonably put on the fronts without rubbing the wells? In the age of $3 gas, I'm willing to trade racket-like acceleration for improved highway mileage.
Also, are there any kits to enable opening the rear triangle windows to improve air-circulation?
