Just picked up my 2018 Scab and been trying to decide what route is best for me. Leaning towards the Eibach springs up front. My concern with those and and any spring for that matter is warranty. Has anyone had issues with dealer and warranty after installing these springs ?
Other than that once I get the Eibachs installed I’ve heard people running 35-12.5 and 37-12.5. Is that possible on factory rims ? The stock tire already looks close to the UCA.
If you’re planning to level the front end, any option whether it’s perch collars, Eibach springs, a leveling kit (not recommended), or new Shocks will have the same result.
The OEM tires are a 315/70R17 which is the same as a 35x12.50R17. The size difference between the two is 0.2” in diameter.
Personally, we don’t recommend running 37s in stock wheels because of the clearance issues you mentioned, but it can be done with the right tire choice.
We prefer the ALPHAequipt wheels which are a 17x8.5 +25 offset. Gives you a little extra tire clearance on the UCA and is confirmed to have full fitment at full compression with the 37x12.50R17 tires and Eibach springs installed.
