What do you guys think I should get, the SLP SFC or teh Kenny Brown SFC?

Both are going to end up costing about the same since I'm in canada, the KB ones I can get from a Canaian suplier, where as I would have to pay duty and such on the SLP.
What ones are lighter?

 

The KB's will give you more ground clearnce. The SLP ones hang kinda low and look like S**t to me. I'd go with them if you want max stiffing. I just went with the DMS tublar, tucked under the car real tight.

 

Which will stiffen the chassis more?
The KBDD's weld and bolt to slightly more attachment points than the SLP.
Lap times with either would probably be identical, or with neither.
