Tiger Cat rear axle dilema
dan8400 - 18/4/06 at 08:52 PM

I have made some seats like rorty's aluminium ones. Quite nice.... Anyway, i am having a job squeezing into my cockpit. The problem is the rear axle mount (sierra IRS). The front mounts sit inside the cockpit, right where the seat (or you arse) is supposed to go. I tried lifting the seats but they made me sit too high up in the car (over 4" lift!!). I have removed the axle and mounted it UNDER the chassis and welded on a new carrier for the diff.. Can anyone see this as being a problem for SVA or strength? The whole axle is held on by two large bolts at the front and 4 small bolts in the diff. (i'm sure everyone knows this) Any help or advice greatly appreciated. Thanks

Tiger cat was a poor choice as it is a poor design IMO... thought i should add that. Wish i had built my own. I will next time, to avoid all the problems i have had with this one.....

ive built a car with the sierra subframe before, its a total dog. Weighs far too much and has poor geometry. How hard would it be to change over to dedion?

Not really sure. Spent most of yesterday looking at the "boat anchor" of an axle scratching my head. It leaves a big gap when you remove it. Might have a tinker with some other designs.... not sure what to do. Is there an easy way (or easier) way to make new rear suspension fit an ill concieved chassis?

I have the setup in my car would be interested in any mods you do re the rear setup. I agree wrong choice of car it seems the thing has been cobbled together with no thought at all. Nothing fits unless you grind a bit here or modify a bit there complete sh1t.

Dave, i totally agree. It seems to be one of the most hated self build cars on the internet!!

just a thought, but what seats do Tiger sell/fit and how do they mount them?


dave1888 - 18/4/06 at 10:29 PM

poxy little seat pads, although Intatrim do some custom seats to fit at about £160 each.

Some pictures of the modifications would be a great help. Does the Tiger Cat retain the large rubber bushes in the axle where it bolts the the chassis? One thing I would be potentialy concerned about is ground clearance if part of the axle assembly hangs below the floor pan.

I will try and get some pics on here later today. The cat does retain the large rubber donut bushes. Ground clearance is slightly less, but i have it set quite low anyway. Not sure if i can cut and weld on some new brackets to bolt to the chassis to keep the sierra axle. Or, if i should tackle it head on and make a whole new rear suspension. I think it's about time i bought "The Book". Might give me some inspiration......

You could try using the Tiger adjustable seats which have the "pigs ears" cut out of them.
But from memory they cost more than the Inertrim models

I believe Tiger have made a pigs ear of most of their budget models

Not sure on what types what (And this isnt directly related to the post), but if you've got one of tigers sevenesque cars thats got a really heavy de-dion rear beam with a sierra diff etc. its a good idea to strengthen up the diff mount.

We have one at DJ that we had to fix for a customer. It had torn the diff out of the mounts when the driver dropped the clutch on a start. You should have seen the bruise on the guys side where it twatted him.

Just a word of warning.
