The Standard ones. You can get a full track season or more out of a set of these for under $300 out the door, and they are surprisingly robust. Not a bad deal at all!
I know this isn't directly the OP's original complaint here, but - I know any number of Mustang track racers who really don't care much for the factory street Torsen for track use. There's a fair bit of personal preference involved in how much and when you want your diff kicking in, depending...
Fair enough. I think 275 is pushing it on 9" rims for a performance application anyway - 285's would be pretty squirmy on those rims. So that makes sense.
While I'd agree the 71R has more ultimate dry grip, I really don't know that I'd DD them. They'll wear a lot faster than a true street tire like the RE11, and they definitely harshen up your ride. But then again, hey - I'm not a 20-something anymore, I need to get some ride quality out of my...
For most of NASA's history, a CAI with a tune was a +1 point mod in Time Trial car class builds. Vents on a stock hood were also a +1 point mod. A catback exhaust, for example, was a +2 mod. This type of rating was derived from countless competition timed runs across the States, and designed...
Nor would I - won't matter without full exhaust, at least not much.
I'd like there to be more gains. I'd also like to be the next King of the Brits. That won't happen, either.
My response will likely be different, due to what I'm looking for. So, disclaimer added...
I've seen many of these CAI and tuning debates over the years. On most modern cars, assuming a basic levels of mods, CAI's don't do much. Not *nothing*, but expressed as a percentage of total engine...
Proper backing plates, high-temp lube and CDC Anti-Squeal spray do wonders. As well - slotted rotors do help this, particularly on dusty pads.
Trust me - you don't know what combating brake noise is until you've done it on an EVO X...
Nothing fancy about your rear pads, then - they are the same as any other modern-era GT. You're looking for a basic stock replacement.
A quick question first - are you using backing plates and anti-squeal spray or lube? If no to either, that's worth a try.
Otherwise, Hawk HPS is worth a...
Skimping on brake pads has probably retired more HPDE drivers from ever showing up again at events than anything else I can immediately think of.
If I literally did nothing else to a noob's car to prepare for a DE, I'd make sure the tires were good, flush the brakes with Motul 600, and use...
This is a winning plan :first: Back in the day, I had a few seasons of mixed HPDE/summer street driving on RE11's, and you'll be happy. Great sidewalls, sharp turn-in, good feedback - very predictable tire that lasts!
One final note - I would try and cure you of the idea that you can or would want to try and use an R-comp like an NT01 as a DD summer tire. Not only is that an egregious waste on a non-preparred surface, but even though they are among the longest lasting R-comps, they still begin to turn to...
Honestly, as long as snow isn't in the equation, RE-11's sound perfect for you. They do dry and wet astonishingly well, and cold is OK too, although you wouldn't want to get too crazy when it's cold. Do these on your stockers.
This lets you get a perfect set of 18's and appropriate tires...
I heard once that there was actually something to the "5w20 design" theory regarding the evolution of the 5.4 3v Tritons - something about the cam phasers requiring a ludicrously high level of oil pressure in later years that you wouldn't achieve without really thin oil. Could be BS, who knows...
Good deal, will take a look. I personally think the near-universal 5w20 recommendation over the past several years is a sop to EPA and CAFE regulations, and to an extent a dodge by car manufacturers. While the EPA and car companies want it to be as thin as possible for best MPG without doing...
