Has anyone used SLP's bolt on SFC's? I like how they are bolt on since I dont know how to weld and dont want to pay someone to have them installed. They look real nice but I thought I would come on here and see if anyone has an opinion about them before I buy them.

 

Yes indeed, they are top notch! I have had them on about 3 years now and when they arrived they were 'beefier' than I could have ever imagined. There were absolutely no issues with the install as they bolted in with all the necessary hardware being included and use pre-existing holes under the car. They strengthen the chassis from front to back and side to side which is much better than most sub-frame connectors. Since they tie in to the mounting point for the stock tunnel brace - I would suggest to you and anyone using these - to go ahead and upgrade to an aftermarket tunnel brace as well as I did. I used the BMR Tunnel Brace/Drive-shaft Loop combo which provided chassis stiffening as well as a DS Loop for the track. Everything is rock solid and I have had no issues - and also have no rattles or flex in the car as well. Some will argue about weld-ins being better - however, the only way I believe that could be possible is if you first used a double-diamond design like the SLP's or Kenny Browns and then welded them in - and even then - that would all rely on the skill of the person doing the welding as I have seen regular subframes that were welded in very poorly which really diminishes their effectiveness. Good luck!

 

SFC's should be welded in.... that is all...

 

Check out the Handling & Braking section:

The weld-in vs bolt-in debate is a long one....
Buy what you are more comfortable with.
Bolt-in will work fine.

Here is a good install write-up for SLP SFCs:

Do a search in the Handling & Braking section (use the Advanced Search). You'll find plenty of good info there

 

I have heard the general idea is that welding will keep the suspension dynamics a lil more tighter versus the bolt ins...i would agree with jaberwaki on this one..weld em..

 

I have the bolt-on SFCs I definately noticed a difference. car felt a lot better, like the susp was doing the work and there was less body creaking. I'm sure welding is better but bolt-on will definately help!

 

thats a good way to say it right there...

bolt in is better then none at all ..... but weld in will be even better

 

anyone in LA or San luis Obispo areas know of a good place to have them welded in? ive read some posts where they havent been welded in correctly and I dont want to waste my money...

 

I live in SLO. I just have bolt-in. I tried central coast spring in santa maria but they said their welders were too HD for that type of thing. Maybe Heacock in Arroyo Grande (10-15mins south of SLO). There has to be a shop more in the LA area. I'd check the sponsor lists for that area.
