B3 S2 vs B4 S2 coupes - chassis question

[UrS4boy]

Is there a B4 S2 coupe chassis or is it just the B3 chassis with B4 hood/bonnet and other bolt ons. I know the S2 avant and sedans (all 316 of them) were B4 chassis but I thought there was a B4 coupe chassis too.

Straighten my brain out.

Please.

Coupe is B3 at the rear hence the dodgy handling at speed

Sorry, I don't understand. Is the chassis different and the suspension the same in 1993 vs 1990?

There is no B3 and B4 Coupe (S2 or not), there is only Typ89 Coupe. It was facelifted with B4 parts at some point but that does not change that fact that all the Coupes are typ89 Coupes.

Edit:Typ85 & Typ81 Excluded ofcourse.

i was under the impression they had chassis differences, wheelbase length and obvious body changes i.e wings, bonnet etc?

i dont know this but would like to learn myself

The coupé has the same rear suspension as the B3. They where not facelifted with B4 hood etc as the coupé was first with these things. So the coupé chassis suspension is the same as B3 quattros

b3 ??the year of theese? the s2 soes have similar part as the mod 81 too....

I see now that the B3/CQ/S2 coupe rear suspension is one A-arm and a MacPherson strut attached to the wheel bearing housing (which is attached to the A-arm) whereas the B4 rear suspension has an upper and lower A-arm, a curved wishbone wheel bearing housing and a shock and spring that attach to the lower A-arm not the wheel bearing housing.

Thanks for making me learn something new.

Any S2 moving at speed would fee dodgy for you mate, cos you're not used to it

There are some differences between the coupes and S2's, but the only thing I can think of is the bolts from the wheel bearing housigs to the strut(post 92' vs pre 92') S2.

UrS4: The Coupe doesn't have an upper and a lower A-arm, that only goes for the avant.

B3 coupes has fittings for the front swaybar in the A-arms vs the S2 where it's in the struts. Older B3 coupes does not have separate struts and wheel bearing houses, and no rear sway bar at all.
