man I read posts all the time that are like subframes are awesome, I can feel so much difference, car is so much tigher.

Well I got weld in subframe connectors and I don't feel jack. I think they just added a ton of weight.

 

I agree, I never quite understood that myself. If youre a vert owner mabey you would notice a big diff etc. BTW I'm not saying it's not a good mod, it's a great mod. Im just saying it's odd people swear up and down they were able to feel such a big diff.

 

I have installed welded in Spohn Tube type Sub Frame Connectors four years ago. When people ride in my car for the first time they can not belive how tight and rattle free it is. For your info the car is 1987 IROCZ and its 19 yrs old and I am the original owner.. I would say they they helped.

 

as soon as you make some real power you will notice compared to a car without

 

4th gen chasses are pretty stout to begin with. I have no excessive squeaks or rattles in none of my three 4th gens, they all have over 90K miles on them and none have subframe connectors (one of them makes about 400 rwhp and another makes around 350 rwhp). There are few people who road-race and/or auto-X their 4th gen cars and have no problems without subframe connectors (one of them gets his car checked at an alignment shop frequently, and the chassis hasn't deflected one bit after all the road-racing events). So I am still not sold on their effectiveness, although they might be useful for drag-racing cars that make insane amounts of power and have a good suspension setup that allows them to launch nice and straight.

 

sell 2 of those and mod the hell out of one then you will be sold

 

Nah, why have only one of a good thing when you can have three Plus cornering fast is more appealing to me than mega horsepower and 10 sec timeslips.

 

you sell 2 go for 8 sec timeslips lol

 

My car acually rattles more then it did before. ALot more, most of the noise is comeing from the rear hatch I think.

 

You can't even begin to compare a 4th gen and a 3rd gen for chassis stiffness.

 

I did sfc's and lca's at the same time so its a little harder to say what did what, but, I noticed the difference in bite off the line, and definitely "feel" more of the road than b4. Unfortunately when the road sucks *****, its like driving on train tracks, and im only 3/4" lowered with bilstein BTS. But at high speeds on good pavement, there is a difference, the car is more stable feeling and high speed lane changes no longer give the car that "shifting" feeling. BTW, I have nitto 555r's on the rear. If you're just spinning street tires from a launch then you just wont understand. The sfc's make the car more rigid and act/react as a whole, not tweak because all that holds the car together is sheet metal. You may not permanently tweak your chassis from alignment to alignment with only 400 HP but I assure you under load like a nasty launch on good tires with nothing but traction, you will definitely twist the chassis w/o sfc's. These things have been around forever guys, and its sure not because they dont do anything. They may not be for everyones ride, but anyone whos serious about racing pretty much uses them so explain that.

 

Got a set of Global West and the car will sit on 3 jack stands now, it wouldn't before.
Ya will wrinkle the roof if ya hook it hard a few times without them,Or your tops will not fit and leak and worst of all the hatch.

 

What kind of subframe connectors do you have and was the car level when they were installed? Something doesnt sound right if you have rattles and such. Mine tightened up the car unbelieveably and as in the post above the car will now stand up on 3 jackstands. Before if i took one out you could see the car start to twist.

 

The car was level and there in solid. I got the granatelli ones.

maybe your car was already twisted from a accident or previous owner???
