Ive decided to take the plunge and do fats and skinnies.On the older 86-93 we would use the 165 sr15 tires,im a bit concerned that my FAT car (3600 lbs) and the wonderfull:rolleyes: NJ roads would kill them.Does anyone have a slightly larger tire in the front that works well?Im going with 15x9 Pro-star XP's in the back and 15x4 front(if they make them,if not 15x3.5)

They make 15x5, 15x6, 15x7....

I don't drag race as much as the next guy, so skinnies to me isn't any smaller than those I listed.

I have yet to buy rims and tires, but I want the same ones you do.

Call me a wuss... :cool:

I just ordered Bullit springs to drop the car a bit,and im gonna wait on the rims and tires,but i want to know what i should get.I had a friend of mine bend a Convo Pro and waste a front skinny on a pot hole,i really just dont want to have to deal with that.

i just got my set of pro star xp's in 2 days ago. I got them from wells performance, but the smallest they make the wheel in right now is the 15x6 and the largest is the 15x9. I have both of these. Im putting a 195 tire on the front and a 295 or 305 on the back. They are not true skinnies but it wil do for my daily driver.

I just have to say that aside from looking REALLY UGLY , skinnies are unsafe on the street and of NO little or no value at the track. being that most of your stopping power is aplied to the front wheels, why would you take away from your traction? Also, I have read and heard numorous testimonials from drag racers who said that skinnies did not help their ET even 1/100 over their stock rims up front. So whats the point?
Just my unsolisited opinion

LOL!

So going from a wheel with a 245/50/16 radial tirethat weighs 50lbs, to a ~13lb(?) wheel and TINY tire, with barley any rolling resistance has little or no help in ET? please explain that one to me. Heck, I see a .1 drop JUST from pumping my 245's up to 60psi! remember that every 1lb of un-sprung weight is like 2lbs of sprung weight...

They are not bad on the street, you just have to REMEMBER that they are there! your not going to be tearing up twisties anytime soon, but you will still out stop and out handle most of the economy cars out there, so I wouldn't worry too much....

Dude, I have talked to friends and read about people many times who got nothing from skinnies (.000). It COULD be worthwhile for the track ONLY not on the street, esp if you have enough power to go wheels up for wieght tranfer. Dont our porky SN95s have a bad enough underesteer problem without throwing a pair of 80s retro looking moped tires on the front? Personaly, Im not into slowing to 10 MPH to go around exit ramps.

Looking "REALLY UGLY" is a matter of opinion. I've gotten more compliments on how my looks in the past 7 months than I have in the previous 5 years I've owned the car. As far as being unsafe on the street, please explain.

As far as exit ramps, I have no problems taking them at the rated speed (even long sweeping curves). With my stockers on there I usually take it at 15-20 MPH over the limit but with the skinnies I do have to slow down some. As long as you "remember" you have skinnies on the front there is nothing wrong with driving them on the street.

As far as gains at the track, I haven't raced much this year so I can't honestly say that they are worth it yet. My combination is in real bad need of tuning (not to mention needing some new O2's) so I don't think I've been able to benefit much from them. I can tell you that I might not have run any faster but I have run more consistent if that's worth anything :D

Have you actually tried them? or drove a car with them? I have talked to friends that say blowers are not worthwhile, and heads and cams suck. Catch my drift?

No crap the car isnt going to handle well with the skinnies, that is not there intent. Just remember that they are there and you will be fine.

When you actually have experience with them, THEN post, until then believe what you like.

I was at the track when my friends ET didnt drop. Does that count? I have never jumped off a vridge but I hear it hurts. Anyway, EVEN if it did help your ET it is NOT for the street.

was the weather the same as every other night he had been at the track? there are a ton factors.... if they DIDNT help, then what exactly is the point of EVERYONE running them who does? they are wroth it, and they do help et's. Heck, the weight savings alone is worth .1, the rolling resistance lost is worth probably the same if not more. How can you say that removing almost 100lbs of unsprung weight from the front of the car is going to not help ET at all?

I personaly noticed a difference on the street...

tell me again why they arent for the street? you can still outstop most economy cars, prolly out handle them too...i know our 95 conertable with 3.5" skinnies will outhandle and outstop my 92 toyota corolla, does that mean my toyota isnt for the street either?

Skinnies were worth .15 for me, even on space saver rims (back in the day) My good friend Jeff also dropped .2

I've ran skinnies for 2 years, no problems whatsoever. Skinnies are for the street just as much as your set of 90/10s.

Maybe your friend couldn't drive consistantly, but EVERY car I've ever seen strap on a set of skinnies, has gained.

Ok its official, your on crack, I saw a consistent .1-.2 improvement.....over 40lbs of rotational mass, not to mention un-sprung mass is a lot.

My friend put a 100 shot of NOS on the car and its slower too....:rolleyes:

Thanks for the replies....sorry for the argument;)
I happy to like both lowered road car look and fat and skinny.Point is,my car is more drag race than road handling.The idea of the 195 fronts crossed my mind,would you be able to post some pics Stroked5.0?I am going for the 295/50 rears for sure.I drive my car once a week,im not so concerned about the "danger" of the front tires,ive driven many cars like this.I just dont want to blow them out cause of the car wieght and the terrible roads.The 195 front sounds like the answer.Thanks again.

I tried the MT Sportsman fronts, (8 ply for heavier cars) After 2 went bad (huge sidewall bulges) I went with cheap 165's from a local tire store. No problems since. The rolling resistance and unsprung weight are the point of skinnies. I can't see the logic in Fordman50's replies, but then again I don't have 1000+ posts. Maybe I spend too much time racing and not enough time posting :eek: I'll have to work on that.
Not.

Yeah I raced a 91'ish looking Fox body that had skinnies up front we ran all the way up to 100 mph weaving in and out. The skinnies didn't really seem to hold him up any. Although I will admit I thought he was a little brave to do that drive hard on skinnies at somewhat high speed. But he kept up with me handling wise. Didn't win.....but kept up with me. I've always heard that it was worth a tenth in the quarter and that it did improve consistency over all. I think however that if your concerns start with how the skinnies will affect your driveability , particulary in a region where road conditions are not ideal, I would probably advise against it. I mean unless you are up to consistently taking considerations for the smaller tire size and driving appropriately depending the situation. However, what you need to ask yourself is , "can the car be driven the way that I want to drive?"
