Which Iso combo for slight rake on vert with H&R Race Springs?

[94vert50]

Will I have a slight rake leaving all stock Iso's in with H&R race on a convertible, OR should I run MM Iso's on top in the rear to make sure I have a little rake?

I'll be running 295/35/18's in rear and 275/35/18s in the front. Don't want to remove any iso's. Thanks in advance for any input.

I wouldnt go with mm iso's and race springs they wont drop your car much, if at all

I have no isos up front, and both stock isos in back, and theres a slight rake, but honestly i thought it would look better, so Im planning on removing the back isos too.

He may not want to drop the car much, if it all. What's your ride height currently? Are you running 17's or 18's? Or, if you have a picture, that'd be a nice reference point. I'd like to keep my rake and only drop the car about 3/4" all around.

My biggest question is this: Will the H&R Race Springs give me a very slight rake even before I start messing with the isolators? If so, I am going to replace all the stock isolators. If not, I'm going to use the MM iso's on the top in the rear.

Thanks for the help!

For everyone's reference, I e-mailed MM. See below.

"We have the following information from actual measurements we took on a
solid-axle equipped Mustang. The front will be the same for an IRS car.
For the rear we have taken no measurements, but I expect it would follow a
similar trend.

Removing Old Rubber Isolators lowered the car:
Front 0.63"
Rear 0.31"

Changing from Old Rubber to Urethane raised the car:
Front 0.38"
Rear 0.44"

Changing from no isolators to Urethane raised the car:
Front 1.00"
Rear 0.75"

Using this information and extrapolating for your questions:
" How much if I only install only the MM isolators only in the top or
only in the bottom versus stock?"
About half of the above dimensions. It might be different depending on
differences in the thickness of the upper and lower isolators.

" If I only install the MM isolators in either top or bottom of the
spring, would you recommend them in the top or the bottom?"
Keeping the upper isolator in place provides much better location for
the spring, as well as retaining most of the noise damping characteristics.

Thanks, MM for the great support!
