Oh also, came across this product that should allow me to run the rear toe + camber I want at a higher ride height: https://drifttec.co/products/high-to...ets-e36-e46-z4

I'm still undecided on them though. My biggest concern is binding, since there has to be a lot less clearance from the bracket to the bushing to allow for the extra toe adjustment. This image shows the difference in geometry pretty clearly:


I'll likely just leave it alone for now and reevaluate when I change springs/dampers/get an alignment.

Is the toe adjustment range an issue?

How are you securing the line from banging around?

I just let it dangle but you could zip tie it. Or use a bulkhead fitting and fab a bracket that is welded or bolted to the frame rail. In fact...I might end up doing that!

Was pretty hot here yesterday, so took that as an opportunity to torture my car's cooling system on the highway and grab some data with the new rad. Ambient temps were ~40C and AC was on full blast.

Did my best to go WOT wherever I could to really stress the engine. Was able to get it hot by doing one of two things:

1. WOT at 2.5k-3k rpm in sixth going up a hill
2. WOT from 5k to 8k in third, then engine brake back down to 5k and repeat ad nauseam

Here's the data with a couple interesting points highlighted:



Was seeing 5-10C across the rad, which seems totally acceptable given the conditions. Think the most important part is that this drop was consistent, regardless of whether I was cruising or really beating on it. Sounds like the car is ready for another hot track day stress test.

Racecar grade zip ties is my guess
