Depending on how the car will be used, stainless brake lines would be a cheap but good mod..If you want a better dedicated oil cooler i'd get the advan unit or something like that, the CPE unit is a secondary cooler, and I haven't heard great things about it. Not bashing CPE, generally speaking they make great stuff. GL with your build!
