Took the car down to National Tire Warehouse for some new rubber.. after much research I decided on the Dunlop D60 A2 JLB's for their combination of price and performance. It's quite hard to find high performance tires in the correct size for the MGB's stock 14" rims. I calculated the original tire diameter of 155/78-14 to be 23.519" and so I got the Dunlops in 195/60-14 or 23.212" which is only 1.305% smaller than original. My new 14 inch "Dan Gurney Victory Mags" are 6" wide which is the mininum for these tires - I think they look quite aggressive without being ridiculous. Unfortunately on the "new" side (green quarterpanel), the tire is rubbing on hard cornering when the car is loaded, so that will have to be sorted out. Driving impressions: WOW!! The new tires are extremely sticky. Road noise is also down tremendously, and even the steering feels lighter even though these tires are wider. Since I got them mounted with a proper balance job, all traces of wheel shake are gone right up to ~ 90 mph. Combined with the new sills and freshly rebuilt suspension, the car feels like its on rails. I also took the chance to put on my spanking new K&N air filters. They were hard to locate, as they are Euro P/N 56-9095 and I had to order them from the UK. Moss used to carry them, but now they carry a different K&N setup. These particular models are large enough to fit the TWM induction horns *inside* of them - the other models are not. The combination of free-flow filters and horns, assuming you have a good manifold and free-flow exhaust setup on the other end, will give a boost of several horsepower. Even though my exhaust is stock, I could tell a difference immediately in throttle response. I had to enrichen the mixture on the carbs by 4 flats - the old foam filters must have been extremely restrictive. The car feels like its pulling stronger as well, and the gas mileage seems slightly better. The engine compartment is starting to look pretty trick, when its cleaner I'll take a photo. Some pics of the (now dirty) final result - dig the nice two tone paint scheme! It's going to get even more interesting when I put the new boot lid and bonnet on.. but the main thing is that the car is now ready (minus fitting the rollbar) for the autocross season starting in March!!
