the larger your tires are, and the faster you run, the more your tires weigh. Throw some 16" skinnies on the front.

it wouldnt really effect et enough (probably not a noticable ammount) to warrent not upgrading brakes/wheels unless you are serious at the track. then skinnies wouldnt be a bad idea if thats your concern but in terms of being any slower than the wheels and tires you have already....probably not.

Those sizes are close. If you search you could most likely find a rim/tire combo that is lighter than what you're currently running while getting the 17's so you can have the 13" brakes. The question is are you willing to pay for it?

Why do you want 13 inch brakes anyway?

The reason for the 13in brakes is the fact that the cougars are very heavy.

That is the reason for the 13in brakes on my car. I would put them
on there and not be worried about the track times dropping much.

Just my 2cents

what fastcat said the car is strapping over 128 mph in the 1/4 mile and it may be better than that if i add some more timing, basically the 11 inch brakes werent cutting it, also the 98 gt wheels should look good

another question is swapping the 94 mustang spindles gonna throw the camber outta whack? i know i had to compress the spring more to be able to bolt up the strut, ill check the alignment this week, cause i hope to have it back on the track by sunday my rear rotors will be ready tomorrow

the words heavy and cougar dont really belong together. FoMoCo hit the power to weight ratio about perfect on these car for sport/daily use. With a v8 anyways.

and for the e.t.,

the wider tire causing that much more rolling resistance might cost you a tenth or two, doubtful you loose much more. Im at a loss to some peoples aspects of wider tires though, unless its a weekend driver the wider tires are not much help in foul weather. ie. hydroplaning and things of the sort. I guess what they loose in versatility they gain in dry traction though.

well yeah...every time you mod your car for performance, you lose an ammount of streetability. tis the nature of the game. on the other hand, a new set of 245s or even 275s arent going to hydroplane any more than a 225 if driven reasonably.

not sure i got this. tbirds and cougars are porkey. i do think they are over exaagerated when people call them heavy, but they arent light. with the stock engines and aods in them they feel just gross. my tbirds werent much heavier than my new edge but my new edge is heavy too.....

Atleast the new edge car had 285HP which is alot better than
the 150HP NonHO Cougars
