I'm looking at getting a set of SFCs in the near future, and am unsure as to which I should go with. I like the added support of the double diamond design vs. the straight design, but my question is do I really need the DDs? My car is primarily a daily driver with the occasional track visit. I have yet to make a pass since the new motor, but expect to be in the mid 12 sec range on motor with a good possibility of a 150-175 shot in the future. I have never been to a road course or in an autocross event, and don't plan on getting into either anytime soon. Which SFCs would you guys recommend? Thanks.

 

If i was you...i'd go with the BMR boxed ones.... Or summit has some other kind on sale for like $87 and they are pretty good ones. Just my 2 cents

 

I think the DD type are the best design because they involve the most mounting points. SLP and Spohn make DDs too. Still, any SFCs are better than none at all. The BMRs are nice because they have a lot of weld points at the rear since they surround the LCA mounts.

 

i have kenny brown DD's and i loves them somethin good!

they're steep, but i think it was money well spent...

besides, you should plan ahead...dont just buy cheap crap now, only to change it a year down the road.

 

go for the BMR boxed ones.....theyre very strong and made a huge difference on my car -- they're only $159.99... www.bmrfabrication.com

IMO DD's are too heavy

 

I agree. DDs weigh too much. Go with some boxed/tubular SFCs. They do the job just fine. I got my BMRs from Thunder Racing and I think they're actuallty $10 cheaper than BMR's site. Either way you cant go wrong.

 

if he's concerned about ~10lbs, then maybe he should go for something lighter.

dd's weigh more because the steel is thick and reduces flex and offers more support, so i think that the weight is well worth it.

 

Yes DD definitly can cut into your exhaust options. Torque arm options as well.

My big beef with DD is that they are uneccesary...IMHO Heres my reasoning why. When you jack the car up by one corner is it seeing more torsion on the frame then it will ever see on the street. Compare a car before and after a 'weak' tubular sfc install. Its the same result as a DD install before and after, very little deflection. I'm not saying that the DD aren't stiffer, i have no doubt that they are, they are just overengineered IMO.

 

For daily driving, you don't need the "best" design. And I doubt, that DD SFC's will make any difference in lap times on road racing course...

 

I have the boxed BMR ones. they are great, BMR recently redesigned them and they tuck in under the car real well now. cant even see the letters BMR thats written on the side of it.

 

The last time I checked Double Diamonds subframe connectors put you in a higher class at an SCCA event.
Thats how much difference they make.
I have them on my car.
Having said that you don,t need them for a daily driver/weekend racer.
they are overkill, the only reason I put them on my car is at the time I had money to burn.
Get some BMRs and you will be fine.

 

Thanks for the input guys. I guess I'm going to have to go with the regular design if I get them soon. A friend of mine is doing a LT1 to LS1 swap and I'll be getting his coated LTs and true duals. The duals will more than likely be temporary, but they'll be on the car until summer for sure. I am planning on having the SFCs before Christmas as long as money allows.
