Just ordered them today. Super smooth Sale. Great Customer Service.
I'm so pumped. I bought the 2 Point Bolt-In Set. Can't wait for some extra traction come spring!!
Thanks UMI & BYUNSPEED

I bought UMI SFC's on group purchase from UMI. Their huge, very well painted, TIG welded and weigh alot, but thats okay. I dont really even need them since I have a coupe. ohh well...
they didnt fit that great, I had to do some bending, I installed them myself (MIG welded).
I guess I like them, but shouldnt have paid so much....

Well I'm making decent power. I can't get traction for anything, and people who have seen my car launch from behind say the car is twisting bad. I ran a 12.9 @109.25 with a 2.150 60ft. So the power is there, i just gotta put it to the ground.
I'm adding on headers come March, so I will have an even bigger increase in power.
I'm hoping these will help out, I'm not looking for a miracle, but I will also be adding some better tires as well.
Hopefully they work out well together

12.9 doesnt really put you in "chassis twisting" territory if you ask me and its normal for cars to torque over on a launch, just means you need an air bag in the right rear spring and maybe a stiffer swaybar if you really want it to leave straighter.
Traction isnt really an issue of chassis integrity in these cars. you'll see MUCH better improvements in traction just with some good sticky slicks, so much traction you'll probably grenade your 10-bolt the first time you take it to the track. after that, LCA's and a torque arm will help you plant better.
If you spin a lot now, put sfc's on, you'll still spin a lot.

Which SFC's of ours do you have? Out of the many sets we have sold and installed we have never had an issue or problem. What part did you have to bend to make it fit? Also I am not sure if you will find a SFC more reasonable priced then what we have to offer.
In terms of traction what they are trying to say is. If you are putting out a large amount of torque and flexing the chassis the SFC's are going to help distribute the weight as well as a much straighter launch.
Hope that helps,
Ryan

People run 12.5's with that kinda mph, plus I'm adding headers for another 20hp at least.
I don't expect SFC's to make all the difference in the world, but I do think they will transfer weight a lot better than right now especiallyw itha nitto 555r.

I put weld-ons on a few months ago after I noticed that I had developed creases in both quarter panels - and, as you can see from my sig, my car is hardly a torque monster. I'm going to have the creases taken out by a dent doctor dude and then will see if the SFC's prevent them from coming back.

Hi, Ryan,
I'm not complaining or anything. I think your SFC's I bought on group purchase were a good price and good quality. They probably were bent during shipping or bent during install, it wasnt that hard to bnd them to the correct shape.
I wish I had t-tops so I would actually NEED them. LOL

FYI, my vehicle isn't a spring chicken. It's over 148K, and has had many AX and RR miles on it, however like some say here, unless you're really pulling some serious drag burnouts (4K-5K RPM launches) with some seriously sticky shoes, that's where the SFC's can make a difference.
