I'm going to take my car to a shop and want to make sure they weld my SFC's in the right places. Does anyone know the places where they weld the SFC's to the body. I have the Alston Racing SFC's from TDS and I'm going to bolt them in and take them to a shop. I heard that the car has to be on it's own weight to bolt them on but it's almost impossible to get down under there cause there's little clearence between my spoiler and the ground. I have the car on four jackstands and the car is level. I was planning on bolting the SFC's with the car like this. Is this OK?

 

It sounds like you're planning to bolt them in yourself. Level gound, then drive the front onto ramps (or jack up the front, then place ramps under tires and lower car onto the ramps) jack the rear by the pumpkin of the differential and place jack stands under the axle. I recommend a shop that installs custom exhaust systems. They'll have the drive-on style lift that's needed and MIG or TIG welder. The front and rear cups weld to the body. Start at the front. Make sure that you have them far enough forward. Use a rubber mallet or jack to push the cups in place. You did get the instructions, along with the SFC install kit right?

Yes I did. I think I should wait and just take it to a shop to avoid any costly mistakes, thanks anyway for the info Lon.

 

You certainly can install them yourself. You just have to support the front tires and rear tires as if it were on level ground. Front tires on ramps and rear axle supported by jack stands accomplishes this using items you likely have around the house. I have a pair of Rhino Ramps by Biltz. I had to cut off the lip on the very rear of the ramp so it would clear the GFX on my lowered car. The ramps tend to scoot and slide as I try driving onto them. I've even tried the trick of tying a rope onto a hole in the front of the ramp and laying the rope down so I'd drive onto it before hitting the ramps. I find it is easier just to jack up the front and slide the ramps under the front tires and lower it down onto the ramps. If your car is lowered you'll find it easier to crank the tirea all the way to one side to allow clearance for the jack handle so you can pump it. I also have to drive up onto a 2x4 on one side so the saddle of the jack will clear the K-member. Once you have the car in the air, straighten out the front tires before you lower them onto the ramps. Just make sure the rear tires have chocks and parking brake is on. Also concrete is a much better surface than asphalt which can soften when hot allowing the jack or jack stands to sink in. Just sharing the tricks I've learned.

if you don't drive onto the ramps, won't the front tires not sit as if you had been driving? um, i know that sounds kind of confusing but...you get what i'm saying? unless the tires can rotate to let the suspension settle all the way, won't they have a lot of "camber"? which, from what i hear, you don't want when welding SFCs in, right?

 

Not really a problem. I agree there will be a little stiction of the suspension. If you're concerned, just give the suspension a bounce by pressing down on the fender after you've dropped it onto the ramps.

it doesn't really effect anything? if not, that's good to hear... i might think more about doing some SFCs, sooner. i like to do all of my own stuff on my car. so, i don't want a shop to put any on my car.

edit: also, have you ever done SFCs with the car on a 2 post lift?

 

Put a set of carpeted floor mats, carpet side down, knobbies up under the weight bearing end of the ramps. That will keep them from sliding on most surfaces.

I used to have a set of wooden ones that I built a while back that wouldn’t slide no matter what I did to them
