Paul,
Hope these are the right numbers. I couldn=E2=80=99t get a tape inside =
the spring so measured from top to a center point on the spring and =
bottom to the same point. Passenger side measured 6.5 inches, driver =
side 7.5 inches. Top of wheel well to floor - passenger side 28 3/8, =
driver side 27 1/8. Odd showing shorter spring length but slightly =
longer from wheel well to floor. As far as I know, no front end damage, =
tires not showing any odd ware after 10,000 miles (aligned tires when =
they were last replaced). =20
Goodparts.com <http://goodparts.com/> shows spring length of 8 7/8 =
inches (390 lb spring rate), rimmerbros.com <http://rimmerbros.com/> is =
10.35 inches (330 lbs spring rate) and a lowered spring at 9.33 inches =
(420 lb spring rate), Moss Motors has several options but they do not =
list spring height, nothing at bpnorthwest.com =
<http://bpnorthwest.com/>.
Now getting way out into the ether - found a formula for spring =
compression, Fitted length =3D free length - (fitted load/spring rate). =
Fitted load is the hard number to determine. Using some numbers from =
the internet , a TR6 is 2,500 lbs with 48.2% on the front. That would =
be 1,205 lbs on the front (note, saw number of 718 pounds for Spitfire). =
Using these numbers:
Goodparts: 8.875 -(1205/390) =3D 5.785 - shorter than the existing =
springs
Rimmer standard: 10.35 - (1205/330) =3D 6.7 - pretty close to existing =
springs
Rimmer lowered: 9.33 - (1205/420) =3D 6.46 inches
Using the 6.7 number, similar to current ride but would new springs =
compress less on bumps and cornering. Also, is the 1,205 weight in the =
ballpark. And last thought - the current springs have a 1.5 inch spacer =
so they really are compress more than the numbers show. I=E2=80=99m =
guessing that they are offering little resistance to bumps etc.
Last, Alan has used the goodparts springs with minimal rubbing. His =
tire size is 205/60/15 vs. the 205/70/15 on mine. That gives me about =
.8 inches more of sidewall height.
Have I confused the issue too much? Get some springs and see if that =
does the job? Seems like the standard springs from Rimmer would work =
the best.
Thanks,
Frank
