Report KE70/AE71 Differential Upgrade options? in AExx Corolla Discussion Posted June 17 On 6/16/2023 at 3:37 PM, altezzaclub said: Luca, mine is still an open diff, but we have two KE70s up on the farm with LSDs, both OS Gikens. Expensive, but very good and long-lasting. You should be able to find OS G or Kaaz or Cusco for the AE86 diff or the Celica, they are all T-series. The F is heavier, as you say, but if you want to be a trail-blazer, check out the vans at your local wrecker... Thanks altezza! Looks like the ra60 is the way to go. Seems like the cheapest way to get a t series. That paired with a cusco wont cost me ae86 money. Before I buy i will do some measurements on tarago diffs, as i heard they are a good option. Cheers!
