The expenses may just be starting with those tires and other modifications. Now you will get to break parts inside that rebuilt transmission. The differential output shafts and low (granny) gear housing are the parts that now can break on command. You will next find that you need a brake upgrade. Engine upgrade and ring and pinion changes are common with this tire size. But they do look cool.

Subject: Re: Slider Extension

Thanks to all of you for your responses. I had no idea that this mod would be so expensive! In the end, I went ahead and ordered 6,  245/75/16s and crossed my fingers. I had tested this size before, but without the side grippers, so I had them test fit the rear ps and the slider cleared.....so I gave them the go ahead. BTW this Syncro is not stock. All drive train parts are aftermarket, with 930s, fat axles, Burley 16" trailing arms, adjustable front and rear suspension a la Abercrombie....actually, everything down there is new, with the exception of the SVX and the rebuilt tranny......
Amazingly, these tires are only slightly noisier than my all terrain Toyos.
They are Cooper STT Discoverers and they are maybe a little more aggressive than I expected. Pictures to come after din din.......
Thanks again!
Miguel
