(sry if this has been asked before, I couldn't find anything)

I wanted to install some lowering springs (H&R) on my Meg. Asked a local shop with good Reviews (Elferwerk in Baden by Vienna) and got a call from (I think) the owner, telling me that the same car from another customer has been blocking a lift in his shop for weeks, because basically every suspension component...

Megane MK4 RS Suspension Disassembly Problems?]]> Mon, 16 Feb 2026 20:48:14 +0000 https://rsmegane.com/threads/steering-rack.24404/ https://rsmegane.com/threads/steering-rack.24404/ invalid@example.com (eduardbooster) eduardbooster I see PN 490018776R from mine, but there's nowhere I can find a new one. I also looked for PN 490010062R
I've seen some cheap ones in autodoc, they look very similar (except for inner and outer tie rod ends, which I can get elsewhere). Has anyone tried fitting one of these steering racks with the right tie rod ends and seen if it fits right?

Probably it's not like 3RS...

So I'm looking for a "beefy" 18" perfect fittment
Would only go with OZ Ultraleggera and Protrack One.
Now it's on 8x18 ET40 on OEM shocks
Probably would go with KW V2

I was planning something like OZ have in their line
8x18 ET35 (235 40 18) on front
9x18 ET55 (255 35 18 or 265 35 18) on rear

my 250 makes a clunkish sound when changing direction (fwd, bwd), then braking (lightly). Only this formula produces the clunk.

I've found out that it's due to the front pads moving back and forth in the caliper. It has CL5+ pads, and the holes for the pins are significantly larger than the pin diameter.. Has anyone else experienced this problem, or am I perhaps missing some brake hardware that should take care of this?

IIRC, the sound wasn't there just after installation, so it's...

I've gone through 2 sets of outer CV joints for both sides, in less than a year. (OEM SNR)

Is there any stronger CV Joint option for Megane 3 RS ? or anyone experienced this?
Or maybe something I'm doing wrong perhaps somewhere.

Grease is put in place evenly spread, and boots are new and secured in place, no leaks.
The car is mostly a daily but driven quite hard on track 3 times a year.

Current difference to original suspension is stiffer lower balljoints, and wider OZ wheels....

So a long story short, my brembos jammed on and cooked a caliper and damaged the rubber on the ball joints.

I've replaced the wishbone, the top and bottom ball joints and abs cable with pattern parts.
The calipers have been refurbished and refitted with new discs and pads.

New genuine renault track rod arm fitted.

Brakes all bleed profesionally at the abs pump, so dramas there.

Tracking was all done yesterday at my local F1 auto centre.

Cable ties is maybe an option, but then I’m worried about them wearing through if I just cable tied them to the axle..

So, could some kind people who’ve got them show me a way to keep them nice so I’ve got some ideas before I commit to getting them made.

Thanks in...

Can you please advise which anti roll bar bushed fit my car as it appears there are two options.

Unfortunately, my local Renault garage has stopped giving me part numbers.

I need to replace my rear disks because they have annoyingly lipped, despite only wearing 40%, which is causing them to rub.

Does anyone have the part number for the OEM disks?

Can you buy the OEM bushes?
Or do people just go for the aftermarket parts like the powerflex road or black series?]]> 12 Mon, 30 Jun 2025 06:41:54 +0000 https://rsmegane.com/threads/mk3-fender-rubbing-solutions.23271/ https://rsmegane.com/threads/mk3-fender-rubbing-solutions.23271/ invalid@example.com (James M) James M Grabbed some new wheels in 8.5 et45 fitment and whilst they look great, they do rub a small amount on the rear arches. I picked up a fender rolling kit with the intent to get a bit more clearance only to realise that the rear 'over fenders' are plastic and can't be rolled.

FYI - Current setup is mostly standard besides cooksport lowering springs

Has anyone else had clearance issues they've solved before? Can you grind some of the plastic off with an angle grinder? Cheers...

Want something a bit stiffer than grams and cup shock setup I'm currently running but don't want to go too mad into track only. Was thinking something like 70nm front and rear on the springs.

Been looking at AST5100, Nitron NTR R1 or Bilstein Clubsports.

Anyone run any of these for a while and have an option? Particularly for the Clubsports?

Currently leaning towards AST just due to the cheaper cost but also want...

I come to you hat in hand humbly asking for advice.

Basically-

i’m worried about my suspension/steering assembly bushings/links and such.

i haven’t been able to fault find (probably due to incompetence) as to what the problem may be.
(i have already done drop links on both sides)

Symptoms:
- loud audible clunking/knocking when encountering any bumps
- steering drifting - not major amounts (at high and low speed)
- pulling either way under acceleration and braking
- cornering...
