Built my car last year and used this forums for information. It was extremely helpful. I rarely post anything online but want to contribute to an amazing community. My car has darn near everything you can do to it other then turbo and engine internals. Exhaust, brakes, suspension, intercooler, trans/engine/dogbone mounts, rear sway, and on and on. I did not do adjustable end links after a 1.3 inch drop. After a lot of reading I decided to go ahead and do them.
DON'T PASS ON ADJUSTABLE END LINKS! It's a absolute must! After lowering the car steering was more firm. I thought it was the firmer springs and shocks. After putting the adjustable end links on up front it was a world of difference. The steering is now very easy and much more like stock. The front end links had to be extended almost the 1.3 inches the car was lowed. Slightly less but very close. The amount of tension on the front sway bar was a lot and it made for a much different drive. The car would turn in to easy before, like it was "loaded" and ready to turn. It was also stiffer to turn the wheel. Once the front adjustable sways where installed/adjusted it made a huge difference. It don't matter if your lowered for looks or performance. Adjustable front end links are necessary. Without them you will have pretension on the front sway bar and it will effect the way your car drives. You can get away with it but it's not correct to leave the stock ones on with a lowered suspension.
