I only replaced the Subframe Bushings. In the near future i will probably do the FTBR Kit. That will come.... once funds arrive.

It was hard for me to justify spending like $700 for the FTBR Kit when my entire IRS Cost $600 lol

Looks awesome as usual. I'm sure you plan to polish the pipes at some point. I had issues with the rear tires slightly cutting into the fender so I put iso's on the bottom of the rear and it made a great change in ride as well as just enough height to not cut the tires.

I gotta fix the exhaust still and install the rear hangers to get them aligned perfectly.

Do you plan on getting a rear dif brace or maybe the ford racing setup that includes an upgraded housing from FTBR?

Very nice. Any opinions on the handling and ride?

I'm waiting to get my diff back from the shop with 4.10 gears and the upgraded differential cover. Gah can't wait. Gotta polish my exhaust as well.

Blast from the past. I was wondering if you had a part number for that distribution block and did you have to change your companion flange from you SRA to the IRS? Getting ready to do the swap in a fox body! Thanks.

That's the part I used. I changed the flange on the driveshaft as its a much easier change than on the SRA/IRS part. The IRS is loaded and it takes a ton of torque to get it back together. Hope that helps.

I have a question...



I don't see many SN95s slammed as low as this one. Is there an after market fender revision of some type that makes the front wheel well contour the wheel better when it's that low? The rear one seems like a better fit.

Great job on the IRS. How much has the handling changed?

It may not be, but that pic looks like it's photoshopped to me.

No fender revisions. Fender are stock all around. Actually, it got lower when I did the IRS swap cause i went to H&R Sport Springs (03/04 Cobra Spec) and it lowered it down alot. I am also running no ISOs in the front and only the Upper ISOs on the back.

The wheels fit the body so well in the front because they are 9 inch wide wheels all around.

The pic is not photoshopped, that is the real ride height. It is that sexy.

I think that's why I thought it was 'shopped. I knew it definitely didn't use to be that low, haha.

No problem man. Your local auto supply shop should have the lines that you need. Be sure the flares are the correct type otherwise you will have leaks. I cut my supply line right above where the pumpkin is and ran the lines from there. I've seen some setups where they put the T on the passenger side and then go to the driver side as well.
