Differences between westfield seiw and sierra sdv
Please could someone tell me the differences between the Westfield seiw and the sierra based sdv kit and the pros and cons of each model.
Is there much difference.

The pros of the SDV is ease of fit for the Sierra donor parts obviously and will also give you an extra wide rear end but this in turn is a
problem.
Most people buy the widetrack conversion for the front for a standard wide track car to bring the tracks more in line and help under steer.
So in short if you buy and off the shelf widetrack conversion it wont work as well as if you had a standard widetrack car(non SDV) or so i'm
told.
I have an SDV (without widetrack) and have had the suspension setup by Trevor at Tranzpower in Chesterfield and can manage 1.39 round Cadwell with 2
people so in my eyes unless you are competing for gold at some point its nothing to worry about.
The extra wide rear gives it a great look from the back in my opinion.
Other things to point out are the lovely wide tunnel for the gearbox to which my type 9 fits lovely (think they will take an MT75 too).
It uses the Sierra upright instead of the widely used Cortina but again no big deal, plenty of kit car manufacturers use them.
All in all i love mine and feel no benefit to go and swap it for the standard car.
One last point is the wheel offset which is more limited to ET35-40 at the rear which again hasnt bothered me. I bought 4 x Caterham 13" wheels
with ET40 at the rear and they sit great!
Give me a nudge on messenger if i can help anymore.

No you shouldnt but beware that there is an MX5 based SDV which will restrict you to the MX5 diff etc if you have Ford based stuff to put in.
The engine bay is big enough to put just about whatever you want in too.
Happy hunting....

The only other thing I'd point out is that most Sierra sdv Westfields will use a diff with push in shafts so makes fitting an lsd unit a little
harder, but there are solutions.
I'm perfectly happy with mine 
I used to be indecisive, but now I'm not so sure

The bolt on shaft diff has the same mountings as push in so I can see no issues fitting them
The hub fittings may be slightly different but not by much

The diff will fit, but you'll need either hybrid shafts or bolt on shafts and new bearing carriers as bearings/shaft dia differ too (afaik).
I have push in, with a disc brake conversion to drum hubs, so if I want to go LSD on my Sierra SDV Westy, it's hybrid shafts of use Quaife ATB
internals with push in shafts.
