ahlman Posted October 17, 2006 Share Posted October 17, 2006 I have put new bigger tires on my subaru brat -87 but now I think the speed is to high for offroading. what is the best thing to do? I have seen many subarus with bigger tires than mine so I gues its possible!? Im sorry for my bad english, but Im from sweden:banana: hope you can understand:) Quote Link to comment Share on other sites More sharing options...

ahlman Posted October 17, 2006 Author Share Posted October 17, 2006 I think you need a transfer case. It will give you a lower "low-range" off-road. There are people on this board that have done it and can guide you through the process. what kind of transfer do I need, and I gues I have to lift the car much to get space for a rear axle under the engine.

mcbrat Posted October 17, 2006 Share Posted October 17, 2006 it all depends on the terrain you're going to be on.... I'm running 30's, but have lots of other mods to help compensate.... something for you would be to get a 3.90 D/R from a 85-89 Wagon... and if you plan to go bigger, then you will definitely need to look into the t-case swap. Nissan 720 or Sammy divorced t-case could work. lot's better gears available for the sammy t-case.... Quote Link to comment Share on other sites More sharing options...
Numbchux Posted October 17, 2006 Share Posted October 17, 2006 not much you can do. adjust your driving style, get slightly smaller tires, or go much taller and really custom for a divorced tcase. Quote Link to comment Share on other sites More sharing options...
Phizinza Posted October 18, 2006 Share Posted October 18, 2006 something for you would be to get a 3.90 D/R from a 85-89 Wagon... Something to note. Here in Australia it is all random which diff ratio you got in the 85 to 89 models. I have seen a 85 with a 3.9, 87 with a 3.7 and a 88 with a 3.7. The 87 was a "sports wagon" and the other two were "touring (high top) wagons." This might be the same in Sweden too, or it might be the same as the US. Look for a sticker on the rear diff that gives a ratio number. Quote Link to comment Share on other sites More sharing options...

In the US at least, it's not based on year, it's turbo vs. non-turbo (or part-time vs. full-time, but for the most part, those are pretty similar). turbo's having the 3.7, non-turbo's having the 3.9 but yes, double check before using anything Quote Link to comment Share on other sites More sharing options...
