Still hoppy like an IPA

After installing the Steeda IRS subframe bushing support kit, wheel hop has been reduced but not eliminated. To supplement, would you all recommend the Steeda IRS subframe support braces or the Steeda billet rear vertical links? This is a street car, so I’m wanting to minimize any increase in NVH.

Curious as to which tires you are running and what pressure.

305/30R20 Michelin PS4S in the rear. They are at the recommended cold pressure of 35 psi.

No sidewall tends to do that.

The braces are an easy add on to what you have give it a try and hopefully it has added more reinforcement. before going for vertical links. I get no wheel hop with just my BMR cradle lockout level 2 though.

I had to add both the braces and vertical links along with the lock out bushings. I now get zero wheel hop no matter what tires or surface I'm on. I did stiffen up the diff bushings too.

The IRS braces would be the next part to install - they are the"Meat" of the soup!!

nah, they are the potatoes. The MEAT is the DIFF lockouts. The diff bounces all over the place and it's the axles and wheels that are tied into the Diff.

Pin the Diff to the IRS. Whiteline pucks are quietest. Next are Steeda Red. Make sure you add the bolt sleeves.

I thought the Whiteline’s were discontinued? I don’t see them on their site

Right, right. Unfortunately they aren't like Beetlejuice, say it often enough they'll come back into being... I should have a kit or two in my collection. I guess I'll start the bidding at 'one meeelion dollars (pinky)'

What I should do is have the guys at emachine whip me up some.

The whole catalog if they try to up sell you on crap like they tried me when I asked for basic suspension upgrades over stock on a highway Cruiser.

I'm running UPR's softer, red (80 shore) diff bushing inserts and bushing sleeves from M6G member GTP. UPR's black inserts are the stiffer version at 88 shore.

There was a touch of diff gear whine at highway speeds with the windows up and the radio off. I switched to Red Line 75W-110 and that quieted it down.

that's high for drag racing attempts. Try more like 28-30. Your short sidewalls aren't doing you any favors either.
