How do find out your strut diameter

[Top Cat]

Have i missed something, I thought the GTi was going TC - Are you keeping it and going all USA with it (low and slow)?

Yep you missed something.  Check out the date of the first post.

The question of the correct strut diameter is ''timeless''.

If you have the smaller brake (256/280 mm; on the caliper you can read ''FSIII''),
you have the 50 mm strut. This is used from 75 HP to122 HP.

If you have a 288 mm or 312 mm (FN3 caliper; read ''Ate'' on front side) or the 345 mm
brake (FNRG), then you have 55 mm struts. These are used from 122 on and
a few 1.9 TDI are equipped with DSG and with all from 140 HP on.

One small correction: to my knowledge all 122bhp cars have 288mm discs so have 55mm struts.

When I needed to find out the strut diameter for the new coilovers I just measured it (took the wheel off and measured the shock absorbers diameter).

Hi Rex,

there are 122 HP TSI with 280mm/FSIII and 288mm/FN3 as well.
There are also some 1.2 TSI 105 HP with the larger 288mm/FN3 (Seat Leon)
to make it even more confusing.

That's why I recommend looking at the brake caliper. Everbody should be able
to clearly read ''FSIII'' or ''Ate'' on front of the caliper. This is 100 % safe.

I was just wondering why so many suspension parts dealers don't know
this simple fact.
