Hi,

We bought a 1303 that was labelled a 1303S (it had a 1600tp with front drum brakes).
For the upgrade I bought a complete 924S undercarriage thats the same as a 944N/A that gave me new, more robust front struts that also allowed me to get rid of the press in ball joints by simply fabricating a new TCA. The new TCA is the same length as original and with the max adjust on the inner pivot and the 924S stub axle I have achieved 1 1/2deg neg camber. The 924S single pot brakes are used along with the drilled stub axle for the speedo (the VW bearing cap even fits the 924S hub). New uprated dampers and springs are added plus a strut brace.
At the rear the alloy trailing arms are used with 924S spring plates, TBs (23.5mm), TB cover and cap. The rear set up provides for big disc brakes, and camber and toe adjustability. The camber adjustability is particularly useful. I modded the rear spec to have 928S4 4 pot calipers as the balance with the standard Porsche single pots is all wrong. I fitted a 944 anti-roll bar at the rear with fabricated hangers (I could have gotten them off the 924S tube) and heim joint adjusters. The driveshafts are 944 (the 924S ones were off an auto car so were different side to side) with VW181 output flanges. New uprated dampers were added naturally. The alloy trailing arms push the track out and the 928 calipers also needed clearance so I fitted wide wings all round. 16" rear wheels with big offsets could solve the extra track and clearance issues.
Getting the whole undercarriage was well worth it as it provides all the bits necessary and should be cheaper than collecting individual items. My 924S undercarriage cost me £65 plus £110 for 928S4 calipers plus £50 for a pair of 944 driveshafts (still got the 924S auto ones for spare CVs) and £100 for the output flanges IIRC. The rear AR bar was £20. New springs, dampers and poly bushes were around £420.
If you want coilover front struts then the 924S ones lend themselves to adding sleeves and 2 1/4" springs (spring rate 100lb/in+).
I wouldn't go for 944T undercarriage as IMO its very expensive and the only upgrade worth having is the calipers over the standard 924S/944 N/A
