Thread: Switching to IFS

Tweet

Although I have no experience with Fat Man, they advertise that they have made IFS for many different chassis. With luck, they may already have a design that will fit yours.

The Carroll Smith book the Tech suggests is a very good primer and will give you a lot of good suggestions on what makes a chassis/suspension work. What it is NOT is a recipe on how to build one that will fit yours like a glove. The book that precedes it 'Prepare to Win' should be included as well. Then there is a third, 'Engineer to Win' to finish the series and I do need this one to finish my collection (Richard, you are costing me $$$$)

Just to be clear, I'm not recommending them, just stating the fact that they have many choices. But with that said, I have looked at their product several times and as late as 6 June and really can't see anything really poorly designed - so is it the installer's fault/poor instructions or is there a deficiency.

I do have a TCI IFS on my TCI chassis - with the caster at 1.5* - and it tracks just fine tho I'll probably add another .5 or so.

Ratzilla's engine is in the back and I have added weight ( 700+ lbs ) to the front . I went to the local dump and weighed it on their scale . With me in it (235 lbs ) the gross weight is 3600 Lbs - yes 36 not 26 lbs . original Fiero if I remember right was 2600 with 1000 on front and 1600 on rear . mine is 1500 front and 2100 rear almost the same ratio as the Fiero . I have a coil over type spring set up in the rear using 450 Lb springs these are the heaviest springs TCI makes . I decided to work on the rear before making a drastic change up front . After doing some searching on coil springs , I decide to install some type of pad or cushion between the top of the spring and the spring perch .BMW among others uses them on their vehicles . Picked up some rubbeer spring stiffiner thingies at the Boys . Spent the aft modifing my spring top pockets to accept them , after some alteration . Will weld them together tomorrow and test em out . Who knows , start with the easy way first . $ 7.50 invested so far . Heidts tech told me 450 's should be enough .pic of old spring top and new spring top with pad installed.

No work again today so I got to finish em up . Bolted everything together and took a spin . Can't believe the difference , like night and day . Am thinkin now , a new set of some good gas shocks on the front and who knows . Any sugestion on the shocks . Bilsteins want 175 for a pair . not against paying for something thats worth it but that's a bit pricey to be throwing parts at the problem .
