Supra LCA i heard is the way to go if replacing lca on lexus sc400. then i also hear about VFT (Vlamos) bushings and stuff. So which is the way to go supra lca or vlamos with stock lexus arms. what to do????? thanks



what about sway bars... any for the sc that are a good idea? will it diminish drive comfort when cruising? thanks.

low mileage new bushings
high mileage new control arms

what he said depends on the condition of your ball joints. IF your ball joints are ok replace just the bushings if not the whole arms.

Actually i think mine are just fine. I just read that the supra arms will be better for handling if you have modded your car performance wise. what do you think?

the arms are almost exactly the same..thats why they work.

almost correct, supra lca have a harder durameter rubber inner then lexus . it gives better deflection under load as opposed to softer rubber for luxury absorbtion

If better performance is what you're looking for then polyurethane bushings in your stock arms would be your best bet.

yes poly bushings in stock arm if balljoints are good (you have been warned its a pain to change the bushings, but will give stiffest ride)
or just plain supra LCA's (more expensive but no burning out old bushings and new ball joint, wont be as stiff as poly but more than stock)

almost correct, supra lca have full rubber bushings. lexus bushings are drilled through like swiss cheese.

the Supra LCA bushings cannot be replaced. but the Lexus ones can.
For the cost that it CAN be to have someoen drill out the old bushings you may as well just get new supra LCA's and have peace of mind that you also have a new Balljoint.

but if your doing the work yourself... i gues you can do either way.
I decided for the supra LCA's as the price difference was a no brainer.

? silly answer.
mine arent bad just looking for upgrade
i think i heard someo negative things about polyurethane bushings that they squeak like crazy? are u running them?
with most things like this i have a shop do. i think supra lca is the route im taking. but wanted to see what all thought about the vlamos and the other options as far as bushings and staying with the original lexus arms. does anyone prefer the stock arms vs the supra arms?
i do not want it to be so stiff where you lose driving comfort. i still want it to have luxury feel just sturdier where you need it. so would that be the supra lca?

czar07

what i meant was there wouldnt be any discernible performance gain from the supra lca, unless youre arms were completely fked.

Eff all that. Go with delrin bushings...if you want performance, I have em but I.am going to order and install new supra lca's when I swap in new steering rack.

I've just replaced all my front bushings, upper and lower control arms with polyurethane on mine for a couple of weeks now, and they really are very stiff. Before I changed it my Tokico blue shocks in front would bottom out from a 5in tall speed bump, but after changing it to poly's it rides like an off-roader now, no joke, I can feel every slab of pavement on the road. So, if you're talking about performance wise, I'd highly recommend doing this. It's only an hour job depending how experienced are you removing and installing the lower control arms. Burning the rubber is really not a big deal, it's very easy with my handy dandy torch.

And oh yeah, I'm gonna be doing the rear also in a couple of weeks. My SC is my daily so I gotta find time.

Okay i understand what you mean now, thanks. so if mine are just fine then supra lca is a waste? because not that big of difference?
Damn thats crazy. If i was looking for pure performance then i would for sure be running those.
