Thread: P38 ride - it seems hard and jiggly

I can only think of shock absorbers being the problem (assuming the car is not in extended mode).

I've been checking and my actual tyre pressures were 34 front 36 rear. I thought they were 30 all round but obviously I was wrong. I've now reduced the pressure in the front to 28 and left the rear alone. I'll see if it makes a difference. I am wondering if it has been a combination of the type of tyres and the pressures.

No, I'm not driving in extended mode. The EAS is working nicely, raising and lowering at all the right points.

Willem,
I would guess at substandard/ worn shocks. I recently fitted a set of Bilsteins to a RR with EAS and it immediately changed the ride quality to how it should be.

I've got the same lower than average ride and would be surprised if it's not the shocks. Everything else (tyre pressure, bags, compressor) is working fine. i just need to be less of a tight arrrs and get new shocks. I hope...

I'm pretty sure my shocks are OEM. Maybe after 147ks they are past their useby date?

Hi Willem

I tend to agree with the others that it is probably your shocks more so than the air springs. However, if the budget stretches to it I'd suggest changing the air springs over at the same time.

I got a set of Bilstein shocks last year from Arnott Industries in the US, much cheaper than buying them locally.

Give Triumph-Rover Spares in SA a call. They have my old RR including the Arnott GenIII Air Springs and Bilstein Shocks. They quoted me a reasonable-ish price to buy them back as spares for my "new" RR, but not reasonable enough to make me commit.

Cheers, Paul.

Gahh! We could have supplied a set of old springs and shocks to fit to it before it went to TRS!

Willem, I recall Scouse had a set of shocks for sale at a good price. I would have bought them except I'd just fitted new shocks to mine.

IMHO a 38A has a more jiggly ride than a RRC with springs.
I drove a friend's 38A and was surprised how much more low speed jiggling it had than my 93 RRC then on 10% uprated springs and Boge shocks and BFG ATKO LT 245.75x16s.
A 38A has lower profile tyres than a RRC and the air springs and I have seen many references to this difference in ride quality in Pom magazines.
I guess it depends what you are used to. My RRC now is much more jiggly after fitting rear air bags and (comfort) Bilsteins.
