48075-24010 / 48076-24010

Today I fitted a pair of these on the inner front lower control arms.

Pretty straightforward to fit. Jack up a bit keeping wheels 'just'on the ground, place safety stands, Loosen 2 bolts, nut and secondary bracket.  Lever arm to reduce tension and slide off. A a wipe of grease on shaft on install to stop corrosion. Tighten up TIGHT ;)

Can be even easier to fit on a hoist at your next service. Should take about 15 mins.

They are meant for the RC-F and GS-F

They have a harder Duro and a bit more rubber fill than 2nd Gen IS_X brackets so locate the arm better when under dynamic loads. 

There are Poly ones available from Super Pro locally and FIGS etc in the USA but I wanted the quietness and no maintenance option.

 

1st driving opinions with just over 200k's today, both freeway and secondary bitumen roads.

Car drives straighter with less constant wheel corrections needed on the freeway.

Small movement of the steering wheel now transfers to movement at the road wheel. (less freeplay effect)

Coming up to intersections under hard braking the tram-lining from wear indentations was negligible :) 

Overall the car tracks like it should of. I also have the inertia damper in the steering wheel that changed the feel but could not control the movement of poor resilient bushes.

There does not appear to be any more noise and I think only a small perception of more road roughness feel at the steering wheel.

Worth the $140 they cost landed.....sure thing

Quick question, are the part numbers for IS250/350 LCA brackets same as for the ISF?

Edit found the answer: ISF RH 48075-30020 , IS250/350 RH 48075-30050 ..   just wondering if the ISF and IS250/350 were the same.. i.e. would the ISF benefit from the upgrade also.  Seems there might be a small difference between the ISF and 250, so the difference may not be as notable on the ISF (going to a GSF LCA).

the ISF has stiffer bushings than the regualr X50's

though aftermarket USRS kits (figs or RR) is pretty much the same
