Hey, I'm pretty new here, but thought I could ask a question and maybe give a little of my own experiance.
The guy's that sell the aftermarket suspension stuff are pretty quick to say you need to replace those factory control arms and springs. I believe they say something like they're stamped steel and weak. Pretty much drilled into everybody's head from day one, if you're going to run your car at the strip, your 60' is going to suffer with factory components. Lot's of guy's (like me) running out and spending their hard earned mod bucks on LCA's when the only mod they have is a shifter and drag radials. I've done it myself on F-body's.
This is the second Mustang I've owned. The 1st I had was a '87 that I bought as a roller, and it was running 11.50ish before it came to me. The only thing done to the back was a cheap set of Lakewood shocks, and a passenger side airbag.
I started out running 1.55 60's in that car, and dropped it down to 1.45 before it got sold. That was at 2950 lbs. 10.5 Drag and 3:73's

Current car is a '94 at 3600 lbs. on 3:55's with a best last weekend of 1.560. There is absolutely nothing done to the rear suspension, and it's just like from the factory. The car leaves very straight.
Trying to say the 4 link on these cars is perfect for drag. I don't see any need to spend the dough on rear suspension until you get in the mid/low 1.5's. I'm sure there is an exception to the rule though. Guy's that have spent allot of money already probably don't want to hear this, but it's the truth. We as consumers have been sold very well by those who make them.

So my question would be; at what point should I expect to need boxed control arms and poly bushings? What about drag springs? Adjustable uppers with spherical bushings to set the all important pinion angle? Why have both my cars left straight with flimsy factory junk?
You don't know what you can do until you try. How many 13 second cars are running around with MegaBite Jr's? :D

Peace!
 
who knows man, whith all that torque maybe some LCA's will make 1.5 go down lower...just my guess. and even if it runs good the way you have it; what about when you decide your horsepower still isnt enough? might as well have the foundation to build on
 
Heres a good comparison...

My car with a good bit more power has gone 1.69 two times and is uaually in the 1.70-1.73 range. My friends car with less power would knock down mid 1.6s (1.64 is his best) all day long. He had a good amount of suspension and I have a stock one. He runs ET Streets and I run slicks. Personally suspension does help. Some cars like it better than others but getting adjustable stuff is your best bet!

Might be the driver and not the car???
My son and I both run this car. My best 60' is a full .15 better then his. He mashes the pedal to the floor just like I do when the light drops. The individual has allot to do with the 60'. Having said that, the car has to be able to stand up to it.

what are your mods?
 
My mods are in the sog, stock motor, stock cam, E7s with valves and a valve job, rockers, intake and all the bolt ons with 3.73s.

His car was a stock motored car (ERnotch on the boards) full exhaust, MAF, pulleys, and such.

He had all the suspension peices. and my suspension is bone stock. My car weighs 3150-3200 at the track, his was 3050 (roughly). As far as driving I have launched this car a million different ways. Every results in tire spin or a boggin situation. I have let others run the car and the 60' was worse. I will say this, when I drive my dads car I dont get good 60's, but he does, yet I run slightly faster times. I have no other way to launch this car (been everywhere from 3500 to 6250, and everything from holding RPm to reving as I dump the clutch) and do plan on buying some suspension peices as funds allow.
 
There’s no doubt that at some point you need to upgrade. I’m just not certain when that is. I think allot of guy’s start with the suspension, and believe they’re getting results. More than likely though, any gains they’re seeing are probably a result of seat time more than anything else. The only true way to judge a mod is for it to evaluate it on its own merit with no other changes.
If someone were to say “I have been running my car for awhile, and when I went to Eibach drag springs, I dropped .03 off my 60’ time”; now that would be something. For the most part, what you read or hear is just speculation, not really based in fact. Not trying to be self promoting here, just want to pass along personal experience.
How many guy’s make it to the serious level where they can take advantage of suspension mods? Most cars get sold off before they get to that point.

Save your money for something else that will make you go faster, and then upgrade your suspension when you need to.
The aftermarket is flooded with suspension parts because anyone can switch this stuff out. It’s the perfect driveway mod, and multi-million dollar industry for the manufacturers. Just an opinion of someone that’s been around awhile.
 
The problem is in my case I run heads up racing, and without suspension your not going to run thenumbers. The guys I run with can cut similar 60's as you, on DRs, with much closer to stock motors (no big heads, no big cams, etc...). If they went out there on stock suspensions, they wouldnt be winning, or even competing. The guys out there trying it are stuck in the 1.7-1.9s, and the guys with the right suspension are in the 1.5-1.6s. Now your car is dialed in, dont get me wrong, it likes what it has, but not every car is like this. Rarely do I see stock suspensioned cars running good 60's and even if they do, the cars with aftermarket parts are running better ones. I guess I will see when I spend the money on some stuff, in my quest for low 12s.
