Here is my opinion on the matter...
You only hack up your car anyway putting in a dual cooler system. Therefore it is really not stock anymore. Just go ahead and put in a front center RUF or RSR cooler system. Much more efficient and a clean install.
To me the RSR or RUF front kit looks better than stock anyway. Plus the fibergalss bumpers will weigh less than the stock bumpers/spoilers so you get the added weight savings
