I am thinking about lowering the front end , by around a inch , just wondered what height other cars are ?
At the moment mine is 28 1/2 inchs ground to wheel arch !
Good morning Ian,
Sounds like a plan - just measured ours - a nadgence under 27" ground to apex of wheel arch - Vredesteins@ 27 PSI. NB Our car is the one on the left…
that is one Sharp looking motorcar!
drop dead beautiful…
My 3.8S is 27.5 with 185R 15 radials at 35 PSI.
My car is similar to yours - 28 1/4" to the wheel arch. My PO put new Kings springs in the front, I expect it is a little high. Car is on 185/80 15s - closest you can get to the original specification: 185R 15. Paul
I did take a few pictures at Stoneleigh day a few years back , and one of my car , with new springs , never on the road , tyres 185 !
quite a diffrence , mine was far too high .

For various reasons, including having all the necessary suspension and tracking equipment available to me. I can say in kerb weight condition a mid 60’s 3.4 S type will be around a maximum of 28 inch standing height, that is floor to top of front wheel arch.
The bit that really matters is that the lower suspension arm is angled about 8/10 degrees below horizontal in the static condition. This will allow the working suspension travel to not have too much effect on camber.
Beware of the situation with the S Type, make sure you are checking the position in a true working weight, all fuel and payload on board as the car tends to droop at the rear with heavy luggage on board.
Thank you NWG , I took the measurement after coming back from a run , my Garage floor is flat , close to a full tank of fuel , hamper full of tools , jack and so on 2 fold down chairs and the like , I have waited to see if the new springs would settle lower , they have around 3000 miles on them now !

My Mk2/340 has I believe the original front springs. I am using Vredesein Sprint Classic 185HR15 set to 35 psi.
The height of the left wheel arch is 27 3/4" and on the right 28"
I have a 67 Mark 2 3.4 also fitted with Vredestein 185 x 15 tires, and my left side is also 1/4 inch lower than the right. I attended a restoration shop ‘open house’ event several years ago and asked one of the technicians why the left side is 1/4 inch lower than the right side. To my surprise, he said that’s the way they should be…
I am interested to see that I am not the only one with a small height difference left to right on my LHD car, left side down.
Looking at the parts book J34 page 257, there is a table that shows some 3.4, 3.8, with RHD had a 1/8" thicker spring packing on the right side which would raise it by about 1/4".
Perhaps this was done so that on a level road with only a driver in the RHD car, both sides would be at the same height. Who knows?
LHD cars do not appear to have this side to side differential treatment, assuming I am interpreting the table correctly.
When I rebuilt my front suspension I did not see any difference in the spacers side to side so the slight puzzle remains for me.
Quite a mystery indeed… maybe someone has the answer to this conundrum
Well it is certainly good for a water cooler discussion!
I am sure the packers are to make sure the springs fitted are of the same height !

Spent over 6 months trying to get the ride height just right…had rear springs reworked, new front springs without spacers…still front was slightly uneven. Ended up cutting a small amount of spring on the drivers side (US) until it was just right. Took multiple attempts until I was happy with the height (2 fingers between the top of the tire and body).
