Default How to RAISE LS400 REAR Suspension ONLY!

I need help and ideas on how to raise the rear suspension on my 1994 LS400 in order to keep my 19"x9.5" wheels from rubbing in the back. I have tried to find a solution for many months now but to no avail. I have ordered the strut spacers from Speedway Motors but they will only fit 5" springs instead of my 5.5" springs.

I have already had the rear struts replaced 2 years ago. I would like to have my rims on as quickly as possible because the factories are completely unattractive. My fronts don't rub because they're 19"x8.5".



EWW





YAYYY

I so like that color is it paint code 4K7? So how many compliments do you get on the color?
Is it the same car in the fist pic? If so why is that so light in color? The last photo is nice.

Yes it did look like the car in the first photo. I had it repainted with two different factory Toyota colors.

What are the wheel-tire specs? Are these the original springs in the car? Various options include: fender shave-pull, narrower tire/stretched, firmer spring rate or all three.

One of our members made a spacer to bolt above the shock/strut mount. The bolts on the mount are usually sufficiently long to add about 1/4". I don't suggest this when there are other easier options like a fender shave or pull.

I have a staggered setup. The fronts are 19x8.5 and the rears are 19x9.5. The rims have a positive 35 offset. The rear tires are 275/40/19 and the rears are 255/40/19. I dont want to do anything to alter the look of the fenders and rolling them won't help because the wheels come past the fender anyway in the rear.

Buying wheels that fit would have been ideal if you don't want to modify the fenders. A roll would probably give you the clearance you need, remember that as the suspension compresses the tires will camber in considerably.

Raising or stiffening the rear suspension isn't the proper way to do this.

Well a friend of mine installed airbags on his car and all of his rubbing stopped when the suspension was raised. The most I'm willing to do is roll the fenders. The rear wheels stick out about an inch to 1 1/2 inches past the fender so I don't believe the wheels will camber enough in the rear to miss the fender even with them rolled.

you chose the wrong tire sizes for the wheels. i would have chosen 225/245 with a 35/30 series tire combo. 40-series is too much sidewall for the sizing. it will certainly not fit right, and look donk-tastic (unless that's your goal)!

don't under estimate the amount of camber the car gives when lowered. it actually has a LOT. i would not roll the fenders, i would trim or cut them since the metal is soo thick there that rolling will be difficult and cause waves.

do you have any spacers in the rear? 9.5 +35 won't stick out much if the car is lowered, if at all. Even on a 1st gen LS.

Lexus should have offered that color back then, really looks good.

No spacers but they do stick out with the tires probably an inch. I just don't want to cut the fenders. At this point, different rims are not an option. Plus, I personally don't like the lowered look so that's also not an option. I just want to raise it permanently for a reasonable price.

has the tire rubbed already? try and remove the fender trimming first, which gives you a few more mm of clearance.

you can simulate the full stroke of the suspension by putting a block under the tire and lowering the jack. this would give you a basic idea if it would rub, without actually driving it down the road.

Well the lowest cut on the tire is about 1-1/2 inches down the sidewall from the very top of the tread. This is why I want to raise it because it is rubbing pretty low onto the tire sidewall.

A slight shave of the inner well should be sufficient to give clearance. Otherwise I'd suggest a 265 width tire.

Thank you for your suggestion but I WILL NOT BE CUTTING MY FENDERS.
