Default GRP tyres

Hey guys!
I been running AKA tires but found my self in a hard place now.
My hobby shop will no longer carry AKA but instead carry GRP tires.
Have mostly ran Impacts and were happy with them.
How does GRP stack up against AKA compund and thread wise?
Are they similar on grip and longivety?

Iíve used GRP tyres for the past 8 months.

The Sonic, Cubics and Easy all in X compound are enough variation to find a tread pattern for UK tracks. However a more traditional clay pattern is the Contact which I tried at DXR 2019

I find the wear rate to be excellent, truly really good. Also the rounder profile side wall makes the car less snatchy

I will try Plus bc they look like impacts. Then I will decide if I will continue to ran AKA with the extra hassel or change to GRP.

AKA was always out of stock for me, SO I switched a long time ago.

Have you tried the plus tire? If so how do they stack up against impacts?

Have not tried or own any. I have a bunch of 6mik tires, I am going run if we ever get back to racing. A really underrated tire that probably works just as good as aka, proline. I like how they sit flatter on the rim and foam aligns on ridges of the rim. The other thing is all there patterns are original they have not copied other brands, which I think speaks to there innovation and internal research. However the marketing and info in regards to compounds and patterns is confusing. If they tailored the marketing more to the US I think that would help and they need top name American driver which they donít have. I am going talk with some sponsored proline drivers to get their feedback on how the compounds compare to Prolines and do some testing and will let you know how they work if your interested.

Yeah, that would be awesome to get more inputs from others.
I will try them this weekend and see if they can match the Aka or proline. Will post my findings.

When they were easily available locally, I ran them. Very good tires, the wheel though is very soft, softer than all. Compounds are excellent, you'll be using the X and A most of the time X would be a supersoft compound similar to X4 or SS, A is their soft compound but I feel it's a bit harder than a Soft AKA or X3 Proline. All in all, a competitive tyre, feel free to go for it.

Tried the tire and it’s as good as Aka or proline regarding driveability. But I need to run it a bit more and make some tests and adjustments of my car to see if the laptimes stack up.
Regarding wear, I ran about 1.5L of fuel and the tires still had 1/3 of the treads left and still provided good grip.
I will do more testing this weekend and post my findings.

After some adjustments on the car (same as I used when I ran Impacts) I had around 70 good laps today. My conclusion is that these tires are as good as Impacts. They will handle a 60 min amain and still have about 1/4 of the tread left. After that they will be harder to drive and the car will slide alot more an be harder overall to drive.

Facts:
Aka Impact soft fastest 43.3s, avg. 44s
GRP Plus soft fastest 42.5s, avg 43.4

I will do more tests with this tyre brand.

Fun facts:
David Ronnefalk came today to run on our new track. Damn he is fast but it’s not every day you got the oppertunity to race with a former WC. Learned alot about where to push and different racinglines and of course some setup changes. He did alot of testing on the track.
His fastlap around low 39 I think.

Tried another tread pattern today, GRP Cubic.
Aka gridiron II or holeshots are similar to the tread of Cubic. Also a more responsive tire than Plus.
Ran it in soft compound with the same setup on the car that I had when I ran the plus tire and I really likes this Grp Cubic tires.

Cons:
Wears faster than Plus.
Less grip if you are in the dust.

Pros:
More precise, easier to put the car where you want it.
Less differance during the whole tire life, you notice the tyre wear on lap times rather than the behaviour of the car on the track.
They will handle a 60 min main but then they are done.
They will give the car more rotation in the corners if you set up your car that way. Plus will be more locked in.

Hope this helps!
